2011-09-03[media] drivers/media: do not use EXTRA_CFLAGSArnaud Lacombe
Usage of these flags has been deprecated for nearly 4 years by: commit f77bf01425b11947eeb3b5b54685212c302741b8 Author: Sam Ravnborg <sam@neptun.(none)> Date: Mon Oct 15 22:25:06 2007 +0200 kbuild: introduce ccflags-y, asflags-y and ldflags-y Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command line use. By default, gmake(1) do not override command line setting, so this is likely to result in build failure or unexpected behavior. Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

2011-05-20[media] gspca/stv06xx_pb0100: Don't potentially deref NULL in pb0100_start()Jesper Juhl
usb_altnum_to_altsetting() may return NULL. If it does we'll dereference a NULL pointer in drivers/media/video/gspca/stv06xx/stv06xx_pb0100.c::pb0100_start(). As far as I can tell there's not really anything more sensible than -ENODEV that we can return in that situation, but I'm not at all intimate with this code so I'd like a bit of review/comments on this before it's applied. Anyway, here's a proposed patch.

2010-12-29[media] gspca-stv06xx: support bandwidth changingHans de Goede
stv06xx devices have only one altsetting, but the actual used bandwidth can be programmed through a register. We were already setting this register lower then the max packetsize of the altsetting indicates. This patch makes the gspca-stv06xx update the usb descriptor for the alt setting to reflect the actual packetsize in use, so that the usb subsystem uses the correct information for scheduling usb transfers. This patch also tries to fallback to lower speeds in case a ENOSPC error is received when submitting urbs, but currently this is only supported with stv06xx cams with the pb0100 sensor, as this is the only one for which we know how to change the framerate.

The 046d:08da usb id shouldn't be associated with the stv06xx driver as they're not compatible with each other.

2010-01-17V4L/DVB (13882): gspca - stv06xx-vv6410: Ensure register STV_SCAN_RATE is zeroErik Andrén
The Quickcam Web camera would not produce an image if you removed and inserted the module multiple times without physically power cycling the camera first. By writing zero to bridge register STV_SCAN_RATE (0x1443) the camera works as intended, regardless of the number of module insertions.

2009-09-19V4L/DVB (13009): gspca - stv06xx-hdcs: Reduce exposure rangeJames Blanford
Due to rounding and clipping, exposure and gain settings do not map to unique register values. Rather than read the registers and report gain and exposure that may be different than the values that were set, just cache the latest values that were set and report them. Reduce exposure range from 0-65535 to 0-255 so libv4l's autogain doesn't take forever. Remove vestiges of driver signal processing that is now handled by libv4l.
