From 270f54b83f89ca45cdc4dc1908de30cdbc4845d4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Pouiller?= Date: Tue, 12 May 2020 17:04:04 +0200 Subject: [PATCH] staging: wfx: fix endianness of hif_req_read_mib fields MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The structs hif_{req,cnf}_read_mib contain only little endian values. Thus, it is necessary to fix byte ordering before to use them. Especially, sparse detected wrong accesses to fields mib_id and length.
