Subject: [PATCH] scsi: megaraid: Use sysfs_emit in show function callsbacks
Date: Sun, 7 May 2023 13:22:19 +0530 [thread overview]
Message-ID: <ZFdYszGYVRQQA7LP@yoga> (raw)
As stated in the Documentation/filesystems/sysfs.rst file, it
is recommended that the show() callback function for kobject
attributes strictly utilizes sysfs_emit instead of the sprintf
family of functions.
Issue identified using the coccinelle device_attr_show.cocci script.
