[PATCH] wireless: ath5k: replace snprintf in show functions with sysfs_emit

From: Qing Wang <hidden>
Date: 2021-10-13 03:27:44

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.
