[PATCH 19/23] drm/amd/display: Drop uncessary OTG lock check

[Qingqing Zhuo]

From: Rodrigo Siqueira <Rodrigo.Siqueira at amd.com>

The OTG_MASTER_UPDATE_LOCK_SEL is used for
GSL and OTGs in the same group for selecting
the OTG_MASTER_UPDATE_LOCK from the same OTG. At
some point, it a check was added to see if
OTG is running or not, which is not necessary,
and for this reason, this commit dropped that check.
