[PATCH] wireless: ath5k: replace snprintf in show functions with sysfs_emit
From: Qing Wang
Date: Tue Oct 12 2021 - 23:27:46 EST
coccicheck complains about the use of snprintf() in sysfs show functions.
Fix the coccicheck warning:
WARNING: use scnprintf or sprintf.
Use sysfs_emit instead of scnprintf or sprintf makes more sense.
