[PATCH] vfree and kfree cleanup in drivers/

Browse source 
This patch does a full cleanup of 'NULL checks before vfree', and a partial
cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in
that I only did the files that also had vfree calls in them.  The patch
also gets rid of some redundant (void *) casts of pointers being passed to
[vk]free, and a some tiny whitespace corrections also crept in.
