From 269bd1324fbfaa52832bb3efe9f5105c9146a33a Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 2 Mar 2015 04:00:44 -0300 Subject: [media] media: adv7604: improve usage of gpiod API MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 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. Simplify accordingly. Moreover use devm_gpiod_get_index_optional instead of devm_gpiod_get_index with ignoring all errors.
