Subject: [PATCH] drm/exynos: dsi: propagate error value and silence meaningless warning
Git-commit: 0a9d1e3f3f038785ebc72d53f1c409d07f6b4ff5
Patch-mainline: v5.6-rc5
References: bsc#1111666

Properly propagate error value from devm_regulator_bulk_get() and don't
confuse user with meaningless warning about failure in getting regulators
in case of deferred probe.
