Subject: [PATCH 42/44] tty: cleanup tty_chars_in_buffer
Date: Tue,  2 Mar 2021 07:22:12 +0100	[thread overview]
Message-ID: <20210302062214.29627-42-jslaby@suse.cz> (raw)
In-Reply-To: <20210302062214.29627-1-jslaby@suse.cz>

There is no need for 'else' when the 'if' part already returned. This
makes tty_chars_in_buffer similar to tty_write_room too.
