Subject: [PATCH 4.4 14/22] ALSA: vxpocket: Fix invalid endian conversions
Date: Tue, 21 Aug 2018 08:21:40 +0200 [thread overview]
Message-ID: <20180821055140.175040304@linuxfoundation.org> (raw)
In-Reply-To: <20180821055139.462620042@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 3acd3e3bab95ec3622ff98da313290ee823a0f68 upstream.
The endian conversions used in vxp_dma_read() and vxp_dma_write() are
superfluous and even wrong on big-endian machines, as inw() and outw()
already do conversions. Kill them.
