From 33e49de5dc09b26bf5ea03302a39274dbf68c661 Mon Sep 17 00:00:00 2001 From: Gunnar Kudrjavets Date: Thu, 18 Sep 2025 18:49:40 +0300 Subject: [PATCH] tpm_tis: Fix incorrect arguments in tpm_tis_probe_irq_single [ Upstream commit 8a81236f2cb0882c7ea6c621ce357f7f3f601fe5 ] The tpm_tis_write8() call specifies arguments in wrong order. Should be (data, addr, value) not (data, value, addr). The initial correct order was changed during the major refactoring when the code was split.
