Description
In the Linux kernel, the following vulnerability has been resolved:

drm/msm/a6xx: move preempt_prepare_postamble after error check

Move the call to preempt_prepare_postamble() after verifying that
preempt_postamble_ptr is valid. If preempt_postamble_ptr is NULL,
dereferencing it in preempt_prepare_postamble() would lead to a crash.

This change avoids calling the preparation function when the
postamble allocation has failed, preventing potential NULL pointer
dereference and ensuring proper error handling.
