X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=44596b8c4750d9a2323f52aecdeecf34f6aaa2e0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/atomic: Unify conflicting encoder handling. Currently we use a flag to change behavior in atomic commit whether a conflicting encoder should be enabled or disabled. This is used for the legacy set_config helper, which disables connectors that have a conflicting encoder but not part of the active crtc list. There's no need for this to be handled in atomic commit, it could be done in the set_config helper instead. This will let the atomic check function reject any conflicting encoders, while set_config can disable conflicting crtc's. This makes it possible to recalculate the changed flags in 1 loop.
