Try again:

drivers/net/irda/vlsi_ir.c: In function ‘vlsi_proc_ring’:
drivers/net/irda/vlsi_ir.c:327:39: warning: comparison of distinct pointer types lacks a cast [enabled by default]

The types on each side of the min() expression are different, so the
compiler warns.  You probably need to use min_t() or similar, and
carefuly examine the possible effects of signed overflow etc.
