From f22ab91ae3029a68d45b1892effb0a1115d6926b Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen <lars@metafoo.de> Date: Thu, 16 Dec 2021 19:52:17 +0100 Subject: [PATCH] iio: sps30: Use sysfs_emit() sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it knows about the sysfs buffer specifics and has some built-in checks for size and alignment. Use sysfs_emit() to format the custom `cleaning_period` device attribute of the sps30 driver.
