[PATCH AUTOSEL 5.5 18/41] drm/exynos: dsi: propagate error value and silence meaningless warning

[Sasha Levin]

From: Marek Szyprowski <m.szyprowski at samsung.com>

[ Upstream commit 0a9d1e3f3f038785ebc72d53f1c409d07f6b4ff5 ]

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.
