Subject: [PATCH 06/11] amiserial: use memset to zero serial_state
Date: Wed, 14 Jul 2021 11:13:09 +0200 [thread overview]
Message-ID: <20210714091314.8292-6-jslaby@suse.cz> (raw)
In-Reply-To: <20210714091314.8292-1-jslaby@suse.cz>
Zeroing each member of struct serial_state in probe is fragile and
overly complicated. Do one memset for them all.
