In case of error, the function st_slim_rproc_alloc() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

The newly added st_fdma driver introduces a build warning for
allmodconfig when we add '-Wmaybe-uninitialized':
drivers/dma/st_fdma.c: In function 'st_fdma_probe':
drivers/dma/st_fdma.c:777:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The warning is correct, though this can't happen in practice
as the check is redundant (we don't get to this function if
the pointer is NULL). Even if the function were called with a
NULL of_node, the check is not needed because of_property_read_u32
can deal with a NULL argument by returning an error.
Removing the unnecessary code simplifies the function and avoids
the condition that we get the warning for.

This patch adds support for the Flexible Direct Memory Access (FDMA) core
driver. The FDMA is a slim core CPU with a dedicated firmware.
It is a general purpose DMA controller capable of supporting 16
independent DMA channels. Data moves maybe from memory to memory
or between memory and paced latency critical real time targets and it
is found on al STi based chipsets.
