Subject: [PATCH AUTOSEL 5.4 109/130] iwlwifi: mvm: fix 22000 series driver NMI
Date: Tue, 22 Dec 2020 21:17:52 -0500 [thread overview]
Message-ID: <20201223021813.2791612-109-sashal@kernel.org> (raw)
In-Reply-To: <20201223021813.2791612-1-sashal@kernel.org>
From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit 9e8338ad17eb8976edd5d2def516e4b3346a4470 ]
For triggering an NMI in the firmware, we should only set BIT(24)
in the corresponding register, not the entire mask that's usable
by the driver.
This currently doesn't matter because the firmware only enables
BIT(24), but we'll start using BIT(25) for other purposes with an
upcoming API change.
