From 6db5c15c8b6a4154415041165365acbe7ef623b3 Mon Sep 17 00:00:00 2001 From: Li Zhijian Date: Fri, 15 Mar 2024 13:52:10 +0800 Subject: wifi: b43: Convert sprintf/snprintf to sysfs_emit Per filesystems/sysfs.rst, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. coccinelle complains that there are still a couple of functions that use snprintf(). Convert them to sysfs_emit(). sprintf() will be converted as weel if they have.
