Pawel Osciak f2035364cc [media] s5p-mfc: fix a race in interrupt flags handling
Interrupt result flags have to be cleared before a hardware job is run.
Otherwise, if they are cleared asynchronously, we may end up clearing them
after the interrupt for which we wanted to wait has already arrived, thus
overwriting the job results that we intended to wait for.

To prevent this, clear the flags only under hw_lock and before running
a hardware job.

Kamil Debski e2c3be2aff [media] s5p-mfc: Fix sparse errors in the MFC driver
The following error: "error: incompatible types in conditional expression
(different base types)" was reported multiple times for the s5p-mfc
driver. This error was caused by two macro definitions - s5p_mfc_hw_call
(in s5p_mfc_common.h) and WRITEL (in s5p_mfc_opr_v6.c).

In the former case the macro assumed that all ops return a value, but some
ops return void. The solution to this problem was the addition of a
s5p_mfc_hw_call_void macro.

In the latter case the macro used the ?: construction to check whether
the address is non zero. This is not necessary after the driver left the
development and debugging cycle, so the READL and WRITEL macros were
removed.

Arun Kumar K 77ba6b7396 [media] s5p-mfc: Support multiple firmware sub-versions
For MFC firmwares, improved versions with bug fixes and
feature additions are released keeping the firmware version
including major and minor number same. The issue came with
the release of a new MFCv6 firmware with an interface change.
This patch adds the support of accepting multiple firmware
binaries for every version with the driver trying to load
firmwares starting from latest. This ensures full backward
compatibility regardless of which firmware version and kernel
version is used.

not.

First of all dma_alloc_coherent() returns NULL in case of error.

Pawel Osciak 9d87e8375d [media] s5p-mfc: Don't allocate codec buffers on STREAMON
Currently, we allocate private codec buffers on STREAMON, which may fail
if we are out of memory. We don't check for failure though, which will
make us crash with the codec accessing random memory.

We shouldn't be failing STREAMON with out of memory errors though. So move
the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also,
move MFC instance opening and closing to REQBUFS as well, as it's tied to
allocation and deallocation of private codec buffers.
