sound/oss: Remove unnecessary casts of void ptr
Jesper Juhl [Mon, 8 Nov 2010 23:11:03 +0000 (00:11 +0100)]
The [vk][cmz]alloc(_node) family of functions return void pointers which
it's completely unnecessary/pointless to cast to other pointer types since
that happens implicitly.

This patch removes such casts from sound/oss/
