Subject: [PATCH] staging/rtl8192u: add endianness conversions
Date: Thu, 26 Jan 2017 20:22:00 +0100 [thread overview]
Message-ID: <20170126192200.28863-1-colin@cvidal.org> (raw)
Fields frag_size and playload_size of struct ieee80211_txb are encoded
as short little-endian. This patch adds conversions to / from cpu byte
order when copy / write these values in variables of architecture
independent byte order. It also avoid a sparse type warning.
