From 1ee5ac365c2a554b59b0e7445455d93a0577662b Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 19 Feb 2020 20:34:38 -0800 Subject: [PATCH] scsi: qla2xxx: Suppress endianness complaints in qla2x00_configure_local_loop() Instead of changing endianness in-place, write the data in CPU endian format in another buffer and copy that buffer back. This patch does not change any functionality but silences some sparse endianness warnings.
