Subject: [RFC/RFT 1/7] i2c: sh_mobile: simplify sending address for RX
Date: Wed, 16 Jan 2019 22:05:49 +0100 [thread overview]
Message-ID: <20190116210555.12209-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20190116210555.12209-1-wsa+renesas@sang-engineering.com>
pd->pos won't be smaller than -1, so we can simplify the logic.
