From: Uwe Kleine-König Date: Wed, 18 Feb 2015 12:47:11 +0000 (+0100) Subject: iio: improve usage of gpiod API X-Git-Tag: v4.14-rc1~5616^2~138^2~102^2~27 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b457f53a2afa7de3cecdec1772fbd522b98afc49;p=platform%2Fkernel%2Flinux-rpi.git iio: improve usage of gpiod API 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 outputs.
