[PATCH 083/510] Staging: brcm80211: Remove unnecessary casts of void ptr returning alloc function return values

[Greg Kroah-Hartman <gregkh@xxxxxxx>]

From: Jesper Juhl <jj@xxxxxxxxxxxxx>

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/staging/brcm80211/
