The sparse warnings have changed to this:

  CHECK   /home/fthain/src/kernel.org/linux/drivers/scsi/zorro_esp.c
drivers/scsi/zorro_esp.c:274:14: warning: cast removes address space of 
expression
drivers/scsi/zorro_esp.c:712:14: warning: cast removes address space of 
expression

Why not just call writel() and get rid of the 't' temporary pointer?
