[PATCH][next] ath11k: fix uninitialized variable radioup

From: Colin King
Date: Thu Dec 12 2019 - 14:10:51 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variable radioup is not uninitalized so it may contain a garbage
value and hence the detection of a radio that is not up is buggy.
Fix this by initializing it to zero.

Addresses-Coverity: ("Uninitalized scalar variable")
Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices")
