Subject: [PATCH 41/50] drm/bridge: tc358762: Set pre_enabled on pre_enable to
|
|
prevent regulator imbalance

The RPi cherry-pick moved tc358762_init() to pre_enable but dropped the pre_enabled = true assignment.
|
|
Without it, post_disable always bails out early and never disables the regulator.
