Subject: gpiolib: demote the hogging log messages to debug
X-Git-Tag: v6.5-rc1~158^2~21
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=be6736cc5423e9c153f38ca49ed9ba05a02a58f9;p=tomoyo%2Ftomoyo-test1.git

gpiolib: demote the hogging log messages to debug

Drivers should be silent when they work correctly. There's no reason to
emit info messages when GPIO lines are hogged. Demote the message to
debug.
