[media] uvcvideo: Set error_idx properly for S_EXT_CTRLS failures

2013-01-11T15:30:27+00:00

The uvc_set_ctrl() calls don't write to the hardware. A failure at that point thus leaves the device in a clean state, with no control modified. Set the error_idx field to the count value to reflect that, as per the V4L2 specification. TRY_EXT_CTRLS is unchanged and the error_idx field must always be set to the failed control index in that case.

Drivers: media: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Partly revert "[media] uvcvideo: Set error_idx properly for extended controls API failures"

2012-12-23T17:39:14+00:00

Commit f0ed2ce840b3 ("[media] uvcvideo: Set error_idx properly for extended controls API failures") causes user space to behave incorrectly on one of my test machines (there is no sound under KDE 4.9.4 using pulseaudio and there is a knotify4 process occupying one of the CPU cores 100% of the time). Reverting that commit entirely fixes the problem for me. However, commit f0ed2ce840b3 appears to do more than it follows from its changelog, because the changelog only says about the changes related to ctrls->error_idx, while the commit additionally changes error codes returned by various functions in uvc_ctrl.c and uvc_v4l2.c. It turns out that the changes of the returned error codes confuse the user spce, so it is sufficient to revert the part of commit f0ed2ce840b3 not mentioned in its changelog to fix the problem.

[media] gspca_sonixj: Add a small delay after i2c_w1

2012-12-21T23:26:40+00:00

We already have the same delay in i2c_w8, but it was missing from i2c_w1, adding this delay fixes the Microsoft VX-3000 camera often (but not always) streaming video data with a very green-ish tint. Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab

[media] gspca_sonixb: Properly wait between i2c writes

2012-12-21T23:26:39+00:00

We must wait for the previous i2c write to complete before starting a new one. Sofar we were getting away with this, but it seems that some parts of the usb-subsystem has been sped up making us go to fast :) This fixes streaming on sn9c103 based cams not working with an "i2c_w error" error.

[media] uvcvideo: Fix control value clamping for unsigned integer controls

2012-11-28T12:31:14+00:00

V4L2 integer controls are stored in signed 32-bit values. However, UVC controls can be either signed or unsigned. Take the UVC control signedness into account when clamping the control value to the min-max range. Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab
