Subject: [PATCH] kernel/params.c: Remove sparse-warning (different signedness).

Fixing:
  CHECK   kernel/params.c
kernel/params.c:329:41: warning: incorrect type in argument 8 (different signedness)
kernel/params.c:329:41:    expected int *num
kernel/params.c:329:41:    got unsigned int *

Signed-off-by: Richard Knutsson <ricknu-0@...dent.ltu.se>

Compile-tested on x86 with all[yes|mod|no]config.
Since 'num' is initialized to '0', then only increments, it can/should be unsigned.
