From a5ba28454b52024ca40ccf9ef3bde390bf9500c7 Mon Sep 17 00:00:00 2001 From: Lech Perczak Date: Tue, 7 Nov 2023 01:29:57 +0100 Subject: [PATCH] mac80211: ath9k-htc: support "chanbw" in debugfs ath9k-htc USB-based adapters also support 5/10MHz channel bandwidth. Move the code handling the features in debugfs to common-debug.c, and create proper registration functions to use in debug.c and htc_drv_debug.c, leaving only debugfs registration there. While at that, refresh one patch that would conflict otherwise. Tested on TP-Link Archer C7v2 (ath79) and TP-Link WN722Nv1 (AR9287) and WN822Nv2 (AR7010+AR9287).
