[media] media: ti-vpe: Use mem-to-mem ioctl helpers

2015-02-02T15:34:18+00:00

1: Simplify the vpe mem-to-mem driver by using the m2m ioctl and vb2 helpers. 2: Align and arranged the v4l2_ioctl_ops. 3: Fixes a typo. 4: Use of_match_ptr() instead of explicitly defining the macro to NULL in case CONFIG_OF is not defined.

[media] media: ti-vpe: use vb2_ops_wait_prepare/finish helper

2014-12-22T16:34:05+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.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

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] ti-fpe: LLVMLinux: Remove nested function from ti-vpe

2014-10-30T12:46:17+00:00

Replace the use of nested functions where a normal function will suffice. Nested functions are not liked by upstream kernel developers in general. Their use breaks the use of clang as a compiler, and doesn't make the code any better. This code now works for both gcc and clang.

media: platform: ti-vpe: drop owner assignment from platform_drivers

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

[media] ti-vpe: Fix typecast

2014-09-26T09:50:58+00:00

Addresses have the same size of unsigned long, and not u32. That removes a warning on 64 bits compilation: drivers/media//platform/ti-vpe/vpdma.c:332:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] WARN_ON(((u32) buf->addr & VPDMA_DESC_ALIGN) != 0); ^ include/asm-generic/bug.h:86:25: note: in definition of macro ‘WARN_ON’ int __ret_warn_on = !!(condition); \ ^ Signed-off-by: Mauro Carvalho Chehab

[media] v4l: ti-vpe: Remove casting the return value which is a void pointer

2014-09-22T22:21:08+00:00

Casting the return value which is a void pointer is redundant. The conversion from void pointer to any other pointer type is guaranteed by the C programming language. Signed-off-by: Jingoo Han Signed-off-by: Mauro Carvalho Chehab

[media] v4l: ti-vpe: use c99 initializers in structures

2014-09-22T21:17:08+00:00

Use c99 initializers for structures. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @decl@ identifier i1,fld; type T; field list[n] fs; @@ struct i1 { fs T fld; ...}; @bad@ identifier decl.i1,i2; expression e; initializer list[decl.n] is; @@ struct i1 i2 = { is, + .fld = e - e ,...}; // Signed-off-by: Julia Lawall Signed-off-by: Mauro Carvalho Chehab
