5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Thomas Weißschuh <linux@xxxxxxxxxxxxxx> Upstream commit 3315e169b446249c1b61ff988d157238f4b2c5a0. The correct way to emit data into sysfs is via sysfs_emit(), use it. Also perform some trivial syntactic cleanups.
