From fdb4a5fcd7458d6cf075d908a499f822a9787fac Mon Sep 17 00:00:00 2001 From: Mathew McBride Date: Thu, 11 Nov 2021 04:06:29 +0000 Subject: [PATCH] drivers: tpm: atmel_twi: do not use an offset byte This driver was broken due to an empty offset byte being prepended at the start of every transmission. The hardware does not mimic an EEPROM device with registers so an offset byte is not required.
