From d0bac0ec89d66f656f77443c8000fa6c36139b66 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Tue, 29 Aug 2023 09:35:42 -0700 Subject: scsi: ufs: Fix the build for the old ARM OABI All structs and unions are word aligned when using the OABI. Mark the union in struct utp_upiu_header as packed to prevent that the compiler inserts padding bytes.
