Subject: [PATCH] video: fbdev: sm501fb: onvert sysfs snprintf to sysfs_emit
Date: Tue, 18 Oct 2022 14:25:48 +0800 [thread overview]
Message-ID: <20221018062548.642910-1-zhangxuezhi3@gmail.com> (raw)
From: Xuezhi Zhang <zhangxuezhi1@coolpad.com>
Follow the advice of the Documentation/filesystems/sysfs.rst
and show() should only use sysfs_emit() or sysfs_emit_at()
when formatting the value to be returned to user space.
