[PATCH 6.1 032/193] wifi: brcmfmac: fix regression for Broadcom PCIe wifi devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arend van Spriel <arend.vanspriel@xxxxxxxxxxxx>

commit ed05cb177ae5cd7f02f1d6e7706ba627d30f1696 upstream.

A sanity check was introduced considering maximum flowrings above
256 as insane and effectively aborting the device probe. This
resulted in regression for number of users as the value turns out
to be sane after all.

Fixes: 2aca4f3734bd ("brcmfmac: return error when getting invalid max_flowrings from dongle")
