Subject: [PATCH] Input: imx_keypad - check for clk_prepare_enable() error
Date: Mon, 22 Jun 2015 01:01:18 -0300 [thread overview]
Message-ID: <1434945678-8027-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@freescale.com>
clk_prepare_enable() may fail, so we should better check its return value
and propagate it in the case of error.
