[PATCH] tpm, tpm_tis: correct tpm_tis_flags enumeration values

From: Lino Sanfilippo
Date: Tue May 30 2023 - 12:43:13 EST


From: Lino Sanfilippo <l.sanfilippo@xxxxxxxxxx>

With commit 858e8b792d06 ("tpm, tpm_tis: Avoid cache incoherency in test
for interrupts") bit accessor functions are used to access flags in
tpm_tis_data->flags.

However these functions expect bit numbers, while the flags are defined as
bit masks in enum tpm_tis_flag.

Fix this inconsistency by using numbers instead of masks also for the flags
in the enum.
