Subject: [PATCH v3 4/4] tpm_tis: Disable Interrupts on the ThinkPad L490
Date: Fri,  4 Dec 2020 18:43:40 -0700	[thread overview]
Message-ID: <20201205014340.148235-5-jsnitsel@redhat.com> (raw)
In-Reply-To: <20201205014340.148235-1-jsnitsel@redhat.com>

The interrupt storm detection code detects the issue on the ThinkPad
T490s, but the L490 still hangs at initialization. So swap out the
T490s for the L490 in the dmi check.
