2013-10-17[media] marvell-ccic: drop free_irq for devm_request_irq allocated irqWei Yongjun1-1/+0
irq allocated with devm_request_irq should not be freed using free_irq, because doing so causes a dangling pointer, and a subsequent double free.

2013-09-26[media] videobuf2-dma-sg: Replace vb2_dma_sg_desc with sg_tableRicardo Ribalda1-6/+8
Replace the private struct vb2_dma_sg_desc with the struct sg_table so we can benefit from all the helping functions in lib/scatterlist.c for things like allocating the sg or compacting the descriptor. marvel-ccic and solo6x10 drivers, that use this API have been updated.

2013-08-22[media] marvell-ccic/mmp-driver.c: simplify use of devm_ioremap_resourceJulia Lawall1-8/+0
Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2013-07-26[media] marvell-ccic: add SOF / EOF pair check for marvell-ccic driverLibin Yang1-4/+26
This patch adds the SOFx/EOFx pair check for marvell-ccic. When switching format, the last EOF may not arrive when stop streamning. And the EOF will be detected in the next start streaming. Must ensure clear the left over frame flags before every really start streaming.

Remove g_chip_ident. This driver used some of the V4L2_IDENT defines, replace those with a driver-specific enum. This makes it possible to drop the v4l2-chip-ident.h define as well.

2013-03-24[media] v4l2: pass std by value to the write-only s_std ioctlHans Verkuil1-1/+1
This ioctl is defined as IOW, so pass the argument by value instead of by reference. I could have chosen to add const instead, but this is 1) easier to handle in drivers and 2) consistent with the s_std subdev operation.
