Subject: [PATCH] ath11k: Initialize complete alpha2 for regulatory change
Date: Wed, 21 Oct 2020 16:05:55 +0200	[thread overview]
Message-ID: <20201021140555.4114715-1-sven@narfation.org> (raw)

The function ath11k_wmi_send_init_country_cmd is taking 3 byte from alpha2
of the structure wmi_init_country_params. But the function
ath11k_reg_notifier is only initializing 2 bytes. The third byte is
therefore always an uninitialized value.

The command can happen to look like

  0c 00 87 02 01 00 00 00 00 00 00 00 43 41 f8 00

instead of

  0c 00 87 02 01 00 00 00 00 00 00 00 43 41 00 00

Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices")
