Subject: [PATCH] wifi: ath12k: sanitize ath12k_mac_allocate() return code
Date: Tue, 13 Feb 2024 11:09:06 +0100
Message-Id: <20240213100912.459018-1-arnd@kernel.org>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

From: Arnd Bergmann <arnd@arndb.de>

The return code has no initializer:

drivers/net/wireless/ath/ath12k/mac.c:8006:9: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized]

Make it return -ENOMEM for allocation failures and remove the unused
variable instead.

Fixes: 6db6e70a17f6 ("wifi: ath12k: Introduce the container for mac80211 hw")
