Subject: [PATCH] mmc: renesas_sdhi: simplify execute_tuning
Date: Thu, 13 Feb 2020 17:37:15 +0100
Message-ID: <20200213163715.8212-1-wsa+renesas@sang-engineering.com> (raw)

After refactoring, 'ret' variable is superfluous. Remove it.

Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

Tested on a Salvator-XS (R-Car M3-N). Tuning to HS400 works,
checksumming a large file works with no performance regression.
