Subject: OMAPDSS: TFP410: use gpio_set_value_cansleep
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=af461d64e11f81db4a7619dd574fe779ae3a0884;p=linux-beck.git

OMAPDSS: TFP410: use gpio_set_value_cansleep

The Beagleboard xM gpio used for TFP410 powerdown is connected through
an I2C attached chip which means setting the GPIO can sleep. Code that
calls tfp410_power_on/off holds a mutex, so sleeping should be fine.
