19dbdbfb747ad7afed88dc7661697744ce192d3b | Analyze and fix the following issue in the Linux kernel code: drm/msm/a5xx: remove null pointer check on pdev | Problem Details:
The call chain on a5xx_gpu_init is such that pdev is not going to be
null, so the null check on pdev can be removed. This also cleans up
a static analysis warning where pdev is dereferenced before the null
check which cannot actually occur.

The "submit->cmd[i].size" and "submit->cmd[i].offset" variables are u32
values that come from the user via the submit_lookup_cmds() function.
This addition could lead to an integer wrapping bug so use size_add()
to prevent that.
