Subject: [PATCH v2 06/17] staging: wfx: fix endianness of fields media_delay and tx_queue_delay
From: Jérôme Pouiller <jerome.pouiller@...abs.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.
