Commit Message

Fernando Ramos Oct. 7, 2021, 7:37 p.m. UTC
Refactor places using drm_modeset_{lock,unlock}_all() so that they only
appear once per function.

This is needed so that in the next commit I can replace those functions
by the new macros (which use labels that can only appear once per
function).
