[PATCH] tpm/tpm_tis: Disable interrupts for MSI GS66 Stealth 11UG

From: Jonathan McDowell
Date: Thu Aug 10 2023 - 05:21:28 EST


The MSI GS66 Stealth 11UG laptop also suffers from an IRQ problem with
tpm_tis, causing the TPM to be inaccessible. Add an entry to
tpm_tis_dmi_table to force polling mode.
