[media] media: platform: exynos-gsc: Constify platform_device_id

2015-05-12T06:48:01+00:00

The platform_device_id is not modified by the driver and core uses it as const. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Kamil Debski Signed-off-by: Mauro Carvalho Chehab

[media] media: exynos-gsc: use vb2_ops_wait_prepare/finish helper

2014-12-22T16:34:35+00:00

This patch drops driver specific wait_prepare() and wait_finish() callbacks from vb2_ops and instead uses the the helpers vb2_ops_wait_prepare/finish() provided by the vb2 core, the lock member of the queue needs to be initalized to a mutex so that vb2 helpers vb2_ops_wait_prepare/finish() can make use of it.

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

[media] platform: Make use of media_bus_format enum

2014-11-14T19:54:08+00:00

In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in all platform drivers.

[media] vb2: stop_streaming should return void

2014-04-23T13:12:51+00:00

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.
