From 40e171c2d306e42057433fb2c2f1fee2d385e1c4 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 30 Jan 2023 13:11:41 +0200 Subject: dmaengine: use sysfs_emit() to instead of scnprintf() 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.
