[PATCH][next] drm/msm/a6xx: Remove logically deadcode in a6xx_preempt.c
Posted by Everest K.C. 1 month, 2 weeks ago
The ternary operator never returns -1 as `ring` will never be NULL.
Thus, the ternary operator is not needed.
Fix this by removing the ternary operation and only including the
value it will return when the `ring` is not NULL.

This was reported by Coverity Scan.
