Subject: [PATCH v1 1/2] extcon: axp288: Add missed error check
Date: Thu, 25 Jul 2019 23:34:04 +0300	[thread overview]
Message-ID: <20190725203405.65523-1-andriy.shevchenko@linux.intel.com> (raw)

It seems from the very beginning the error check has been missed
in axp288_extcon_log_rsi(). Add it here.
