From 86da8be35c00e01b8b277896d8e81fb33bf22d06 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 29 Jun 2022 01:17:45 +0300 Subject: mfd: intel_soc_pmic_bxtwc: Use sysfs_emit() instead of sprintf() sysfs_emit() is preferred over sprintf() when formatting the value to be returned to user space in show() functions, because it knows about sysfs buffer specifics and has sanity checks.
