Subject: [PATCH 2/2] mdio_bus: use devm_gpiod_get_optional()
Date: Mon, 12 Jun 2017 23:55:39 +0300 [thread overview]
Message-ID: <20170612210551.696721345@cogentembedded.com> (raw)
[-- Attachment #1: mdio_bus-use-devm_gpiod_get_optional.patch --]
[-- Type: text/plain, Size: 1451 bytes --]
The MDIO reset GPIO is really a classical optional GPIO property case,
so devm_gpiod_get_optional() should have been used, not devm_gpiod_get().
Doing this saves several LoCs...
