Subject: [PATCH] regulator: slg51000: Fix a couple NULL vs IS_ERR() checks
Date: Thu, 08 Aug 2019 10:33:35 +0000 [thread overview]
Message-ID: <20190808103335.GD30506@mwanda> (raw)
The devm_gpiod_get_from_of_node() function never returns NULL, it
returns error pointers on error.
Fixes: a867bde3dd03 ("regulator: slg51000: add slg51000 regulator driver")
