[alsa-devel] [PATCH] sound: fix incorrect use of platform_device_register()

[Akinobu Mita]

The platform_device allocated by platform_device_alloc()
should be added to the device hierarchy by platform_device_add()
instead of platform_device_register().

Otherwise it will hit WARN_ON() in platform_device_register().
by illegal refcount.

This patch fixes such incorrect usages in portman2x4 and mts64 drivers.
Also it removes unnecessary trailing whitespaces.
