Subject: [PATCH 1/1] uio: uio_fsl_elbc_gpcm: simplify getting .driver_data
Date: Sun, 21 Oct 2018 22:01:02 +0200 [thread overview]
Message-ID: <20181021200102.2354-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20181021200102.2354-1-wsa+renesas@sang-engineering.com>
We should get 'driver_data' from 'struct device' directly. Going via
platform_device is an unneeded step back and forth.

Build tested only. buildbot is happy.
