Subject: bnx2x: prevent crash in shutdown flow with CNIC
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6ef5a92cdf5ee65578a287b9a030964b03a538ed;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

bnx2x: prevent crash in shutdown flow with CNIC

There might be a crash as during shutdown flow CNIC might try
to access resources already freed by bnx2x.
Change bnx2x_close() into dev_close() in __bnx2x_remove (shutdown flow)
to guarantee CNIC is notified of the device's change of status.
