Subject: [PATCH 06/24] tty: serial: fsl_lpuart: Drop unnecessary sg_set_buf() call
Date: Mon, 29 Jul 2019 12:52:08 -0700 [thread overview]
Message-ID: <20190729195226.8862-7-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190729195226.8862-1-andrew.smirnov@gmail.com>
Sg_init_one() will already call sg_set_buf(), so another explicit call
right after it is unnecessary. Drop it.
