Subject: [PATCH] wifi: ath11k: fix return value check in ath11k_ahb_probe()
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: 342fcde9d91460f01f65707e16368a1571271a3a
[ Upstream commit 342fcde9d91460f01f65707e16368a1571271a3a ]
ioremap() returns NULL pointer not PTR_ERR() when it fails,
so replace the IS_ERR() check with NULL pointer check.
Fixes: b42b3678c91f ("wifi: ath11k: remap ce register space for IPQ5018")
