Subject: [PATCH 07/13] pinctrl: sh-pfc: checker: Improve pin function checks
Date: Fri, 10 Jan 2020 14:19:21 +0100 [thread overview]
Message-ID: <20200110131927.1029-8-geert+renesas@glider.be> (raw)
In-Reply-To: <20200110131927.1029-1-geert+renesas@glider.be>
Improve the checks for pin function descriptors:
1. Merge declaration and assignment of the local variable for the
current pin function,
2. Pin function names must be unique.
