Subject: [PATCH v5 06/10] i2c: meson: remove variable count from meson_i2c_xfer
Date: Sat, 25 Mar 2017 14:09:03 +0100	[thread overview]
Message-ID: <e4458aee-e22c-70d3-74d8-22b64bda13e3@gmail.com> (raw)
In-Reply-To: <645519b8-93e6-57b1-ae8f-7804c6beb9b1@gmail.com>

Variable count has always the same value as i, so we don't need it.
