* [media] uvcvideo: Set error_idx properly for S_EXT_CTRLS failuresLaurent Pinchart2013-01-111-1/+2
| | | | | | | | | | | | | 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.Greg Kroah-Hartman2013-01-033-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | controls API failures" 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.
