From 4ecd704a4c51fd95973fcc3a60444e0e24eb9439 Mon Sep 17 00:00:00 2001 From: Lino Sanfilippo Date: Tue, 30 May 2023 18:41:16 +0200 Subject: [PATCH] tpm, tpm_tis: correct tpm_tis_flags enumeration values 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.
