Subject: [PATCH 3/4] ARM: nxp-imx8mq-evk: clean up nxp_imx8mq_evk_start
Date: Thu, 19 Dec 2019 16:19:28 +0100 [thread overview]
Message-ID: <20191219151929.19521-3-l.stach@pengutronix.de> (raw)
In-Reply-To: <20191219151929.19521-1-l.stach@pengutronix.de>
Mostly cosmetic changes:
- reduce scope of local variabes
- wrap comment to fir 80 char limit
- check return value from imx8_esdhc_load_piggy
- drop intermediate function that only wraps a single other function
