From ea097de7ec4408fc952041da5560cf8a9ae65235 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Pouiller?= Date: Tue, 12 May 2020 17:04:03 +0200 Subject: [PATCH] staging: wfx: fix endianness of fields media_delay and tx_queue_delay MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The struct hif_cnf_tx contains only little endian values. Thus, it is necessary to fix byte ordering before to use them. Especially, sparse detected wrong access to fields media_delay and tx_queue_delay.
