Domain attribute setting for LLCC is guarded by !IS_ERR
check which works fine only when CONFIG_QCOM_LLCC=y but
when it is disabled, the LLCC apis return NULL and that
is not handled by IS_ERR check. Due to this, domain attribute
for LLCC will be set even on GPUs which do not support it
and cause issues, so correct this by using IS_ERR_OR_NULL
checks appropriately. Meanwhile also cleanup comment block
and remove unwanted blank line.
Fixes: 00fd44a1a470 ("drm/msm: Only enable A6xx LLCC code on A6xx")
Fixes: 474dadb8b0d5 ("drm/msm/a6xx: Add support for using system cache(LLC)")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
