* [media] v4l: rcar-fcp: Don't force users to check for disabled FCP supportLaurent Pinchart2016-09-091-1/+1
| | | | | | | | | | | | | | | | | | | | The rcar_fcp_enable() function immediately returns successfully when the FCP device pointer is NULL to avoid forcing the users to check the FCP device manually before every call. However, the stub version of the function used when the FCP driver is disabled returns -ENOSYS unconditionally, resulting in a different API contract for the two versions of the function. As a user that requires FCP support will fail at probe time when calling rcar_fcp_get() if the FCP driver is disabled, the stub version of the rcar_fcp_enable() function will only be called with a NULL FCP device. We can thus return 0 unconditionally to align the behaviour with the normal version of the function.

* [media] media: platform: pxa_camera: change stop_streaming semanticsRobert Jarzmik2016-09-091-3/+12
| | | | | | | | | | | | | | Instead of the legacy behavior where it was required to wait for all video buffers to be finished by the hardware, use a cancel like strategy : as soon as the stop_streaming() call is done, abort all DMA transfers, report the already buffers as failed and return. This makes stop_streaming() more a "cancel capture" than a "wait for end of capture" semantic.
