[PATCH v2 5/8] drm/msm/dpu: rework vsync_source handling

[Marijn Suijten]

Maybe retitle this to something that more closely resembles "remove unset
is_te_using_watchdog_timer field"?

Well, it's "used", but not "set" (to anything other than the zero-initialized
default). s/used/set?

Patch itself is fine, just think the title could be clearer:
