The legacy media controller userspace API exposes entity types that
carry both type and function information. The new API replaces the type
with a function. It preserves backward compatibility by defining legacy
functions for the existing types and using them in drivers.
This works fine, as long as newer entity functions won't be added.
Unfortunately, some tools, like media-ctl with --print-dot argument
rely on the now legacy MEDIA_ENT_T_V4L2_SUBDEV and MEDIA_ENT_T_DEVNODE
numeric ranges to identify what entities will be shown.
Also, if the entity doesn't match those ranges, it will ignore the
major/minor information on devnodes, and won't be getting the devnode
name via udev or sysfs.
As we're now adding devices outside the old range, the legacy ioctl
needs to map the new entity functions into a type at the old range,
or otherwise we'll have a regression.
Detected on all released media-ctl versions (e. g. versions <= 1.10).
Fix this by deriving the type from the function to emulate the legacy
API if the function isn't in the legacy functions range.

The 5 volt detect functionality broke in 3.14: the code reads IO register 0x70
again after it has already been cleared. Instead it should use the cached
irq_reg_0x70 value and the io_write to 0x71 to clear 0x70 can be dropped since
this has already been done.

vpfe_prepare_pipeline()
Add the missing unlock before return from function

video->lock is lock/unlock in function vpfe_open(),

changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data
and vb2_thread") broke videobuf2-dvb.
The root cause is that, instead of calling threadio->fnc() for
all types of events except for VB2_BUF_STATE_ERROR, it was calling
it only for VB2_BUF_STATE_DONE.
With that, the DVB thread were never called.

The vb2_thread implementation was made generic and was moved from
videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately
that clearly was never tested since it broke read() causing NULL address
references.
The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb
pointer in various core functions).
The v4l2_buffer no longer exists after moving the code into the core and
it is no longer needed. However, the vb2_thread code passed a pointer to
a vb2_buffer to the core functions were a v4l2_buffer pointer was expected
and vb2_thread expected that the vb2_buffer fields would be filled in
correctly.
This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the
pb pointer is a void pointer, so no type-checking took place.
This patch fixes this problem:
1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use
a NULL pointer here since they don't care about v4l2_buffer anyway.
2) let vb2_core_dqbuf pass back the index of the received buffer. This is
all vb2_thread needs: this index is the index into the q->bufs array
and vb2_thread just gets the vb2_buffer from there.
3) the fileio->b pointer (that originally contained a v4l2_buffer) is
removed altogether since it is no longer needed.
Tested with vivid and the cobalt driver.

The tda1004x was updating the properties cache before locking.
If the device is not locked, the data at the registers are just
random values with no real meaning.
This caused the driver to fail with libdvbv5, as such library
calls GET_PROPERTY from time to time, in order to return the
DVB stats.

This is a partial revert of commit ed8d1cf07cb16d ("[media] Export I2C
module alias information in missing drivers") that exported the module
aliases for the I2C drivers that were missing to make autoload to work.
But there is a bug report [0] that auto load of the ir-kbd-i2c driver
cause the Hauppauge HD-PVR driver to not behave correctly.
This is a hdpvr latent bug that was just exposed by ir-kbd-i2c module
autoloading working and will also happen if the I2C driver is built-in
or a user calls modprobe to load the module and register the driver.
But there is a regression experimented by users so until the real bug
is fixed, let's not export the module alias for the ir-kbd-i2c driver
even when this just masks the actual issue.

With CONFIG_V4L2=m and VIDEO_SAMSUNG_EXYNOS4_IS=y, we can select the
individual drivers as built-in code when that should not be possible:
drivers/built-in.o: In function `s5pcsis_set_fmt':
policy.c:(.text+0x13afdc): undefined reference to `v4l_bound_align_image'
drivers/built-in.o: In function `s5pcsis_probe':
policy.c:(.text+0x13b440): undefined reference to `v4l2_of_parse_endpoint'
policy.c:(.text+0x13b72c): undefined reference to `v4l2_subdev_init'
Changing VIDEO_SAMSUNG_EXYNOS4_IS to tristate means that the dependency
from CONFIG_V4L2 propates to the individual Kconfig symbols and they
can only be built as loadable modules if V4L2 or any other of the
dependencies itself is a module.

The build of m32r allmodconfig fails with the error:

The build of videobuf2-dma-contig.c depends on HAS_DMA and it is
correctly mentioned in the Kconfig but the symbol VIDEO_STI_BDISP also
selects VIDEOBUF2_DMA_CONTIG, so it is trying to compile
videobuf2-dma-contig.c even though HAS_DMA is not defined.

set with VIDIOC_SUBDEV_S_FMT. Currently it is not the case as

The Media Control framework now requires entities to be registered with
the media device before creating links so commit c7621b3044f7 ("[media]
v4l: vsp1: separate links creation from entities init") separated link
creation from entities init.
But unfortunately that patch introduced a regression since wrong links
were created causing a boot failure on Renesas boards.
This patch fixes the boot issue and also the media graph was compared
by Geert Uytterhoeven to make sure that the driver changes required by
the Media Control framework next generation did not affect the graph.

Like the Yoga 900 models the Lenovo Yoga 700 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.
This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

The extended flash address needs to be subtracted from bcm_tag flash
image offsets. Move this value to the bcm_tag header file.
Renamed define name to consistently use bcm963xx for flash layout
which should be considered a property of the board and not the SoC
(i.e. bcm63xx could theoretically be used on a board without CFE

This adds support for the interrupt controller present on PIC32 class
devices. It handles all internal and external interrupts. This controller
exists outside of the CPU core and is the arbitrator of all interrupts
(including interrupts from the CPU itself) before they are presented to
the CPU.
The following features are supported:
- DT properties for EVIC and for devices/peripherals that use interrupt lines
- Persistent and non-persistent interrupt handling
- irqdomain and generic chip support
- Configuration of external interrupt edge polarity

but kvfree() can handle both kmalloc()ed memory and vmalloc()ed memory
using is_vmalloc_addr(). Unless callers have special reasons, we can
replace this branch with kvfree(). Please check and reply if you found

drivers/soc/qcom/spm.c:305:5: error: 'found' may be used uninitialized in this function [-Werror=maybe-uninitialized]
However, the code is correct because we know that there is
always at least one online CPU. This initializes the 'found'
variable to zero before the loop so the compiler knows
it does not have to warn about it.

If the parameter given to the macro is replaced throughout the macro as
it is evaluated. The intent is that the macro parameter should replace
the only the first parameter to container_of(). However, the way the
macro was written, it would also inadvertantly replace a structure field
name. If a parameter of any other name is given to the macro, it will
fail to compile, if the structure does not contain a field of the same
name. At worst, it will compile, and hide improper access of an
unintended field in the structure.
Change the macro parameter name, so it does not conflict with the
structure field name.
