Subject: [PATCH 41/44] tty: n_gsm, remove duplicates of parameters
Date: Tue,  2 Mar 2021 07:22:11 +0100	[thread overview]
Message-ID: <20210302062214.29627-41-jslaby@suse.cz> (raw)
In-Reply-To: <20210302062214.29627-1-jslaby@suse.cz>

dp, f, and i are only duplicates of gsmld_receive_buf's parameters. Use
the parameters directly (cp, fp, and count) and delete these local
variables.
