From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> [ Upstream commit 4e0e90539bb0e6c0ca3768c642df9eed2118a8bb ] If 'of_device_get_match_data()' fails, previous 'pm_runtime_get_sync()/ pm_runtime_enable()' should be undone. To fix it, the easiest is to move this block of code before the memory allocations and the pm_runtime_xxx calls.
