From 1acdaa34ad17e304d39d83fc9affc2d71c550a13 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen <lars@metafoo.de> Date: Thu, 16 Dec 2021 19:52:16 +0100 Subject: [PATCH] iio: scd4x: 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 `calibration_auto_enable` device attribute of the scd4x driver.
