[PATCH 3.19 004/101] ALSA: bebob: fix to processing in big-endian machine for sending cue

From: Greg Kroah-Hartman
Date: Fri Apr 17 2015 - 10:11:40 EST


3.19-stable review patch. If anyone has any objections, please let me know.

------------------

From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>

commit a053fc318bc5d28cd25168c948255fd48a29ea26 upstream.

Some M-Audio devices require to receive bootup command just after
powering on, while codes in BeBoB driver doesn't work properly in
big-endian machine because the command should be aligned by
little-endian.

This commit fixes this bug. This fix should go to stable kernel.
