Subject: [PATCH] hptiop: fix type mismatch warning


drivers/scsi/hptiop.c: In function 'hptiop_host_request_callback':
drivers/scsi/hptiop.c:378: warning: comparison of distinct pointer types lacks a cast
drivers/scsi/hptiop.c:378: warning: comparison of distinct pointer types lacks a cast

Use min_t(size_t, ...) to fix.
