2014-04-23[media] vb2: stop_streaming should return voidHans Verkuil2-7/+3
The vb2 core ignores any return code from the stop_streaming op. And there really isn't anything it can do anyway in case of an error. So change the return type to void and update any drivers that implement it. The int return gave drivers the idea that this operation could actually fail, but that's really not the case. The pwc amd sdr-msi3101 drivers both had this construction: if (mutex_lock_interruptible(&s->v4l2_lock)) return -ERESTARTSYS; This has been updated to just call mutex_lock(). The stop_streaming op expects this to really stop streaming and I very much doubt this will work reliably if stop_streaming just returns without really stopping the DMA.

Drivers are still on staging - some API improvements for getting EDID data from media inputs/outputs - new DVB frontend driver for drx-j (ATSC) - one driver (it913x/it9137) got removed, in favor of an improvement on another driver (af9035) - added a skeleton V4L2 PCI driver at documentation - added a dual flash driver (lm3646) - added a new IR driver (img-ir) - added an IR scancode decoder for the Sharp protocol - some improvements at the usbtv driver, to allow its core to be reused. - added a new SDR driver (rtl2832u_sdr) - added a new tuner driver (msi001) - several improvements at em28xx driver to fix PM support, device removal and to split the V4L2 specific bits into a separate sub-driver - one driver got converted to videobuf2 (s2255drv) - the e4000 tuner driver now follows an improved binding model - some fixes at V4L2 compat32 code - several fixes and enhancements at videobuf2 code - some cleanups at V4L2 API documentation - usual driver enhancements, new board additions and misc fixups" [ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce indentation in of_graph_get_next_endpoint"). The of_graph_get_next_endpoint() function was moved and renamed by commit fd9fdb78a9bf ("[media] of: move graph helpers from drivers/media/v4l2-core to drivers/of"). It was originally called v4l2_of_get_next_endpoint() and lived in the file drivers/media/v4l2-core/v4l2-of.c. In that original location, it was then fixed to support empty port nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port nodes"), and that commit clashes badly with the dropped "Reduce intendation" commit.

2014-03-03[media] em28xx: implement em28xx_usb_driver suspend, resume, reset_resume hooksShuah Khan1-0/+26
Implement em28xx_usb_driver suspend, resume, and reset_resume hooks. These hooks will invoke em28xx core em28xx_suspend_extension() and em28xx_resume_extension() to suspend and resume registered extensions. Approach: Add power management support to em28xx usb driver. This driver works in conjunction with extensions for each of the functions on the USB device for video/audio/dvb/remote functionality that is present on media USB devices it supports. During suspend and resume each of these extensions will have to do their part in suspending the components they control. Adding suspend and resume hooks to the existing struct em28xx_ops will enable the extensions the ability to implement suspend and resume hooks to be called from em28xx driver. The overall approach is as follows: -- add suspend and resume hooks to em28xx_ops -- add suspend and resume routines to em28xx-core to invoke suspend and resume hooks for all registered extensions. -- change em28xx dvb, audio, input, and video extensions to implement em28xx_ops: suspend and resume hooks.
