We need to check the call to cmd_db_read_aux_data() for the error case,
so that we don't continue and use potentially uninitialized values for
'pri_count' and 'sec_count'. Otherwise, we get the following compiler
warnings:
drivers/gpu/drm/msm/adreno/a6xx_gmu.c: In function 'a6xx_gmu_rpmh_arc_votes_init.isra.12':
drivers/gpu/drm/msm/adreno/a6xx_gmu.c:943:12: warning: 'pri_count' is used uninitialized in this function [-Wuninitialized]
pri_count >>= 1;
^~~
drivers/gpu/drm/msm/adreno/a6xx_gmu.c:948:12: warning: 'sec_count' may be used uninitialized in this function
[-Wmaybe-uninitialized]
sec_count >>= 1;

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.
