| Subject: drm/exynos: dsi: propagate error value and silence meaningless |
| warning |
| |
| From: Marek Szyprowski <m.szyprowski@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. |
