[PATCH] pcmcia: use request_region in i82365

      randy_dunlap <rdunlap@xenotime.net>

Convert deprecated check_region() calls to request/release region.
Add return value check on one request_region().

I suspect that it may do an extra release_region(), which should
generate a warning message from the kernel.
