Subject: spi: spi-coldfire-qspi: enable RuntimePM before registering to the core
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f9b841af4c1c3c3b7ce3552ab5ee5d9c430e9c29;p=linux-beck.git

spi: spi-coldfire-qspi: enable RuntimePM before registering to the core

The core may register clients attached to this master which may use
funtionality from the master. So, RuntimePM must be enabled before, otherwise
this will fail.
