Subject: [PATCH resend] staging: gasket: fix class create bug handling
Date: Sun, 15 Jul 2018 11:38:16 -0700	[thread overview]
Message-ID: <20180715183816.190819-1-toddpoynor@gmail.com> (raw)

From: Todd Poynor <toddpoynor@google.com>

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