From: Jules Irenge
Date: Fri Feb 14 2020 - 15:49:48 EST


Sparse reports a warning at vkms_crtc_atomic_begin()

warning: context imbalance in vkms_crtc_atomic_begin()
- wrong count at exit

The root cause is the missing annotation at vkms_crtc_atomic_begin()
Add the missing __acquires(&vkms_output->lock) annotation
