Subject: [PATCH 1/6] ata: remove reference to non-existing error_handler()
Date: Thu, 11 May 2023 00:52:06 +0200 [thread overview]
Message-ID: <20230510225211.111113-2-hare@suse.de> (raw)
In-Reply-To: <20230510225211.111113-1-hare@suse.de>
With commit 65a15d6560df ("scsi: ipr: Remove SATA support") all
libata drivers now have the error_handler() callback provided,
so we can stop checking for non-existing error_handler callback.
Signed-off-by: Hannes Reinecke <hare@suse.de>
