Subject: [PATCH 1/2] tpm: tpm_tis: Fix UPX-i11 DMI_MATCH condition

From: Peter Ujfalusi <peter.ujfalusi@...ux.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@...r.kernel.org # v6.4+
Fixes: edb13d7bb034 ("tpm: tpm_tis: Disable interrupts *only* for AEON UPX-i11")
