Subject: [PATCH 14/18] staging: gasket: fix class create bug handling
Date: Fri, 13 Jul 2018 22:58:12 -0700	[thread overview]
Message-ID: <20180714055816.223754-15-toddpoynor@gmail.com> (raw)
In-Reply-To: <20180714055816.223754-1-toddpoynor@gmail.com>

From: Todd Poynor <toddpoynor@google.com>

class_create() never returns NULL, and this driver should never return
PTR_ERR(NULL) anyway.
