Subject: spi/s3c64xx: Add missing pm_runtime_set_active() call in probe()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=383382501193dc70fb92393eb585a39f9d39b378;p=linux-beck.git

spi/s3c64xx: Add missing pm_runtime_set_active() call in probe()

Mark device as PM runtime active during initialization to reflect
actual device power/clocks state. This reduces the enable count for SPI
bus controller gate clock so it can be disabled when the bus controller
is not used.
