Subject: [PATCH V2] wifi: brcmfmac: fix regression for Broadcom PCIe wifi devices
Date: Wed, 11 Jan 2023 12:24:19 +0100	[thread overview]
Message-ID: <20230111112419.24185-1-arend.vanspriel@broadcom.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 1357 bytes --]

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")
