[ALSA 1/2] a few more -- continue on IS_ERR from platform device registration

[Rene Herman <rene.herman@keyaccess.nl>]

Hi Takashi

I previously only concerned myself with sound/isa. When I now checked
for more platform_device_register_simple() usages in ALSA I found a
couple more drivers that needed the same patches as already submitted
for all the ISA drivers.

This first one is the continue-on-iserr patch for sound/drivers. This
gets them all.
