Currently the allocations for dceip and vbios are based on the size of
the pointer rather than the size of the data structures, causing heap
issues. Fix this by using the correct allocation sizes.

In the case where !sg_dma_len(sgl) breaks out of the do-while loop
on the first iteration, error variable err has not been assigned
any value and will contain garbage. Fix this by ensuring err is
initialized to zero.
Addresses-Coverity: ("Uninitialized scalar variable")
From: Colin Ian King
Currently there is a while loop that contains a handful of continue
statements that can skip over the assignment of the variable err. At
the end of the loop there is a potiential for err to be unassigned
and possibly causing issues when err is checked for a non-zero value.

The variable status is being initialized with a value that is
never read and it is being updated later with a new value.
The initialization is redundant and can be removed. Also clean
up an indentation.

There is a spelling mistake in debugfs gem stats. Fix it. Also
re-align output to cater for the extra 1 character.

Currently if stream->signal is neither SIGNAL_TYPE_DISPLAY_PORT_MST or
SIGNAL_TYPE_DISPLAY_PORT then variable ret is uninitialized and this is
checked for > 0 at the end of the function. Ret should be initialized,
I believe setting it to zero is a correct default.

Currently the ioctl command RADEON_INFO_SI_BACKEND_ENABLED_MASK can
copy back uninitialised data in value_tmp that pointer *value points
to. This can occur when rdev->family is less than CHIP_BONAIRE and
less than CHIP_TAHITI. Fix this by adding in a missing -EINVAL
