From 720b071102d8fab3f0a2808db3ba76c5ce880b7a Mon Sep 17 00:00:00 2001 From: Jarkko Sakkinen Date: Sat, 3 Nov 2018 02:31:07 +0200 Subject: tpm: access command header through struct in tpm_try_transmit() Instead of accessing fields of the command header through offsets to the raw buffer, it is a better idea to use the header struct pointer that is already used elsewhere in the function.
