6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx> [ Upstream commit a08935fc859b22884dcb6b5126d3a986467101ce ] There are no in-kernel users of MSM_ENC_VBLANK wait type. Drop it together with the corresponding wait_for_vblank callback.
