From 8bc8db9ad26da98ebe2d4f861f03f09ece165694 Mon Sep 17 00:00:00 2001 From: Shiji Yang Date: Fri, 14 Jul 2023 23:09:55 +0800 Subject: ath79: increase the rfkill debounce interval for TP-Link Archer C7 v2 Due to circuit issue or silicon defect, sometimes the WiFi switch button of the Archer C7 v2 can be accidentally triggered multiple times in one second. This will cause WiFi to be unexpectedly shut down and trigger 'irq 23: nobody cared'[1] warning. Increasing the key debounce interval to 1000 ms can fix this issue. This patch also add the missing rfkill key label.
