The uvcvideo driver historically uses the
/* Comment
* style
*/
for multi-line block comments, which is frowned upon. Patches for the
driver are required to use the more standard
/*
* Comment
* style
*/
style. This result in inconsistencies. Fix it by converting all
remaining instances of the old style.

trace isn't a good name as it's not a trace mechanism, it is a
typical debug mechanism.
Rename uvc_trace/uvc_trace_cont macros to uvc_dbg/uvc_dbg_cont.
Rename uvc_trace_param to uvc_dbg_param
Rename UVC_TRACE_<FOO> defines to UVC_DBG_<FOO>
Use ## concatenation in uvc_dbg macros to avoid overly long and
repetitive UVC_DBG uses

Instead of calling prink() inside uvc_trace, use dev_printk(), which adds
context to the output.
Now that we are at it, regroup the strings so the messages can be easily
"grepable".

The URB completion handlers currently reference the stream context.
Now that each URB has its own context structure, convert the decode (and
one encode) functions to utilise this context for URB management.

Replace the __[su]{8,16,32} variant of integer types with the
non-underscored types as the code is internal to the driver, not exposed
to userspace.

There are a lot of places where sequences of space/tabs are
found. Get rid of all spaces before tabs.

Some UVC video cameras contain metadata in their payload headers. This
patch extracts that data, adding more clock synchronisation information,
on both bulk and isochronous endpoints and makes it available to the user
space on a separate video node, using the V4L2_CAP_META_CAPTURE capability
and the V4L2_BUF_TYPE_META_CAPTURE buffer queue type. By default, only the
V4L2_META_FMT_UVC pixel format is available from those nodes. However,
cameras can be added to the device ID table to additionally specify their
own metadata format, in which case that format will also become available
from the metadata node.
[Use put_unaligned instead of __put_unaligned_cpu64]
[Use put_unaligned for the sof field as well]
