Subject: [PATCH v29 15/16] leds: lp55xx: Fix file permissions to use DEVICE_ATTR macros
Date: Mon, 22 Jun 2020 13:59:18 -0500
Message-ID: <20200622185919.2131-16-dmurphy@ti.com> (raw)
In-Reply-To: <20200622185919.2131-1-dmurphy@ti.com>

Fix the checkpatch warnings for the use of the file permission macros.
In converting the file permissions to the DEVICE_ATTR_XX macros the
call back function names needed to be updated within the code.

This means that the lp55xx_ needed to be dropped in the name to keep in
harmony with the ABI documentation.
