[PATCH] i2c: xiic: Fix pm_runtime_set_suspended() with runtime pm enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.
