Subject: [PATCH] brcmfmac: check the return value of devm_kzalloc() in brcmf_of_probe()
Date: Fri, 25 Feb 2022 05:21:38 -0800 [thread overview]
Message-ID: <20220225132138.27722-1-baijiaju1990@gmail.com> (raw)
The function devm_kzalloc() in brcmf_of_probe() can fail, so its return
value should be checked.
