Subject: regulator: slg51000: Fix a couple NULL vs IS_ERR() checks
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7352e72a513fd2757b2fda695a349d86faa4c94e;p=linux.git

regulator: slg51000: Fix a couple NULL vs IS_ERR() checks

The devm_gpiod_get_from_of_node() function never returns NULL, it
returns error pointers on error.
