2010-05-18V4L/DVB: gspca: fixes compilation when input is not selectedMauro Carvalho Chehab
It seems that I merged a wrong version of the patch or that changeset 4d770eeb926d0bc44c0bd68d051d3d2a5568ef41 got mangled somehow: It were missed the #else to avoid compilation troubles. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-02-26V4L/DVB: gspca_main: some input error handling fixesHans de Goede
2 small changes to input device error handling: 1) Make it fatal when we fail to create an input device (it is either this or add checks for gspca_dev->input_dev being NULL in a lot of places) 2) Since we allow gspca_input_create_urb() to fail everywhere we call it, and thus never check its return value, make it void.

2010-02-26V4L/DVB: gscpa_sonixb: Differentiate between sensors with a coarse and fine ↵Hans de Goede
expo ctrl Some sensors only allow controlling the exposure by changing the clockdiv, which means that exposure takes pretty large jumps (for example when going from a div of 1 to 2, the exposure doubles). Use 2 different entries in the controls array for these 2 different types of exposure (always disabling one), and; Add a new autogain algorithm for the coarse exposure case, which normally changes the gain setting, only touching the exposure setting if the desired luminance cannot be reached with gain, and after an exposure change once more first tries gain, etc. Thus avoiding exposure changes, and the resulting oscilation because of the huge steps these exposure controls take.

The gscpa core was not resubmitting URB's when the URB status was an error, this means we will loose URB's (potentially all stopping the stream) in case of sporadic USB issues.

2009-12-05V4L/DVB (13178): gspca: Add support for Winbond W9967CF and W9968CF camera'sHans de Goede
This patch adds support to gspca for the Winbond W9967CF and W9968CF camera's. This is mostly a port of the existing v4l1 driver to gspca (making it v4l2). But this also features fixes to the bitbanging i2c code (send a nack not an ack after reading the last byte of a transfer), which gets rid of the weird errors which were being seen there, and of the smbus_refresh() hack to get around these errors. Also the vstart settings have been tweaked to work with different frequency filter settings.
