Subject: [PATCH] fbdev: omap2: improve usage of gpiod API
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.

Also make use of gpiod_get*_optional where applicable.

Apart from simplification of the affected drivers this is another step
towards making the flags argument to gpiod_get*() mandatory.
