[Freedreno] [PATCH v2 1/3] drm/msm/dpu: split irq_control into irq_enable and _disable
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Mon Oct 9 09:29:20 UTC 2023
The single helper for both enable and disable cases is too complicated,
especially if we start adding more code to these helpers. Split it into
irq_enable and irq_disable cases.
