Subject: [PATCH -next] brcmfmac: Fix a double-free in brcmf_sdio_bus_reset
Date: Tue, 1 Jun 2021 18:01:28 +0800 [thread overview]
Message-ID: <20210601100128.69561-1-tongtiangen@huawei.com> (raw)
brcmf_sdiod_remove has been called inside brcmf_sdiod_probe when fails,
so there's no need to call another one. Otherwise, sdiodev->freezer
would be double freed.
Fixes: 7836102a750a ("brcmfmac: reset SDIO bus on a firmware crash")
Signed-off-by: Tong Tiangen <tongtiangen@huawei.com>
