Subject: [PATCH 01/18] mptfc: simplify mptfc_block_error_handler()
Date: Mon, 2 Oct 2023 17:43:11 +0200 [thread overview]
Message-ID: <20231002154328.43718-2-hare@suse.de> (raw)
In-Reply-To: <20231002154328.43718-1-hare@suse.de>
Instead of passing in a function to mptfc_block_error_handler()
we can as well return a status and call the function afterwards.
