Subject: [PATCH 06/17] staging: wfx: fix endianness of fields media_delay and tx_queue_delay
Date: Mon, 11 May 2020 17:49:19 +0200 [thread overview]
Message-ID: <20200511154930.190212-7-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200511154930.190212-1-Jerome.Pouiller@silabs.com>
From: Jérôme Pouiller <jerome.pouiller@silabs.com>
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.
