* [media] media: mx2-emmaprp: Add missing mutex_destroy()Alexander Shiyan2014-05-23
| | | | | | | | This patch adds the missing mutex_destroy(), when the driver is removed. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Kamil Debski <k.debski@samsung.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* [media] media: mx2-emmaprp: Cleanup internal structureAlexander Shiyan2014-05-23
| | | | | | | | | | | There are no need to store resource struct and IRQ in the driver internal structure. This patch remove these fields and improve error handling by using proper return codes from devm_ioremap_resource() and devm_request_irq().

* [media] v4l: Copy timestamp source flags to destination on m2m devicesSakari Ailus2014-03-05
| | | | | | | | | | Copy the flags containing the timestamp source from source buffer flags to the destination buffer flags on memory-to-memory devices. This is analogous to copying the timestamp field from source to destination.

| | | | | | | | | | | src to dst The timestamp and timecode fields were copied from destination to source, not the other way around as they should. Fix it.

* [media] v4l: Rename vb2_queue.timestamp_type as timestamp_flagsSakari Ailus2014-03-05
| | | | | | | | | | | The timestamp_type field used to contain only the timestamp type. Soon it will be used for timestamp source flags as well. Rename the field accordingly.

* [media] mem2mem: set missing v4l2_dev pointerHans Verkuil2013-06-28
| | | | | | | | | | The m2m-deinterlace, mem2mem_testdev and mx2_emmaprp drivers didn't set the v4l2_dev pointer in struct video_device, even though a v4l2_device was registered correctly. These days this v4l2_dev pointer must be set correctly, so this patch adds that for these three drivers.

* [media] mx2-emmaprp: Add copy time stamp handlingKamil Debski2013-04-25
| | | | | | | | | | Since the introduction of the timestamp_type field, it is necessary that the driver chooses which type it will use. This patch adds support for the timestamp_type.

* [media] media: Convert to devm_ioremap_resource()Thierry Reding2013-02-06
| | | | | | | | | | | Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

* [media] mem2mem-emmaprp: Remove unneeded struct vb2_queue clear on queue_init()Ezequiel García2012-09-15
| | | | | | | | | | queue_init() is always called by v4l2_m2m_ctx_init(), which allocates a context struct v4l2_m2m_ctx with kzalloc. Therefore, there is no need to clear vb2_queue src/dst structs.

* [media] drivers/media/platform/mx2_emmaprp.c: use devm_kzalloc and devm_clk_getJulia Lawall2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using devm_kzalloc simplifies the code and ensures that the use of devm_request_irq is safe. When kzalloc and kfree were used, the interrupt could be triggered after the handler's data argument had been freed. This also introduces some missing initializations of the return variable ret, and uses devm_request_and_ioremap instead of the combination of devm_request_mem_region and devm_ioremap. The problem of a free after a devm_request_irq was found using the following semantic match (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression e1,e2,x,a,b,c,d; identifier free; position p1,p2; @@ devm_request_irq@p1(e1,e2,...,x) ... when any when != e2 = a when != x = b if (...) { ... when != e2 = c when != x = d free@p2(...,x,...); ... return ...; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
