Subject: PCI: dra7xx: Disable pm_runtime on get_sync failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0e2bdb0e7abf4b5170874e415ec42df547916dd3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

PCI: dra7xx: Disable pm_runtime on get_sync failure

Fix the error handling when pm_runtime_get_sync() fails.

If pm_runtime_get_sync() fails, call pm_runtime_disable() so there are no
unbalanced pm_runtime_enable() calls.
