Subject: [PATCH v4 06/10] i2c: meson: remove variable count from meson_i2c_xfer
Date: Tue, 14 Mar 2017 22:51:35 +0100 [thread overview]
Message-ID: <126e80e5-f93f-8c18-f283-65eee94b3a82@gmail.com> (raw)
In-Reply-To: <1a2ecdc8-a326-a7a7-22ec-658fd147daf4@gmail.com>
Variable count has always the same value as i, so we don't need it.
