[PATCH 08/17][trivial] scsi: Remove unnecessary casts of void ptrreturning alloc function return values

From: Jesper Juhl
Date: Mon Nov 08 2010 - 18:20:58 EST


Hi,

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 drivers/scsi/
