Subject: [PATCH 1/2] tpm: tpm_tis: Fix UPX-i11 DMI_MATCH condition
Date: Sat, 12 Aug 2023 02:40:01 +0300	[thread overview]
Message-ID: <20230811234002.2656180-2-jarkko@kernel.org> (raw)
In-Reply-To: <20230811234002.2656180-1-jarkko@kernel.org>

From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

The patch which made it to the kernel somehow changed the
match condition from
DMI_MATCH(DMI_PRODUCT_NAME, "UPX-TGL01")
to
DMI_MATCH(DMI_PRODUCT_VERSION, "UPX-TGL")

Revert back to the correct match condition to disable the
interrupt mode on the board.

Cc: stable@vger.kernel.org # v6.4+
Fixes: edb13d7bb034 ("tpm: tpm_tis: Disable interrupts *only* for AEON UPX-i11")
