ni52: kill the second argument of check586(), get rid of bogus pointer
Passing ISA bus address explicitly cast to char * only to cast it back to unsigned long is dumb; so's passing it at all when it's always dev->mem_start... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jeff@garzik.org>
