From 84eee3c845d377cbe1cae722e8f83344107d709f Mon Sep 17 00:00:00 2001 From: Carl Huang Date: Mon, 17 Aug 2020 13:31:53 +0300 Subject: [PATCH] ath11k: refine the phy_id check in ath11k_reg_chan_list_event For QCA6390, it processes the reg chan list event only for phy0, and it goes to fallback if the phy_id is not valid. For a valid phy_id but not 0, just discard the event.
