Subject: [PATCH 5.19 095/207] wifi: iwlwifi: Mark IWLMEI as broken

From: Toke Høiland-Jørgensen <toke@...hat.com>

[ Upstream commit 8997f5c8a62760db69fd5c56116705796322c8ed ]

The iwlmei driver breaks iwlwifi when returning from suspend. The interface
ends up in the 'down' state after coming back from suspend. And iwd doesn't
touch the interface state, but wpa_supplicant does, so the bug only happens on
iwd.

The bug report[0] has been open for four months now, and no fix seems to be
forthcoming. Since just disabling the iwlmei driver works as a workaround,
let's mark the config option as broken until it can be fixed properly.
