http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f354942cb301fed273f423fb5c4f57bde3efc5b2 converted the check_region() calls in drivers/pcmcia/i82365.c into request_regions. Unfortunately this seems to have broken things. isa_probe() used to call check_region() and then call add_pcic() which would request_region(). Now isa_probe() calls request_region() and then calls add_pcic() which calls request_region() again, this fails and add_pcic() returns immediately without doing all the setup etc. On the face of it the patch below fixes the problem, by not doing the second request region in add_pcic(). I think this is preferable to remove the call in isa_probe() since identify() touches the I/O regions and is called before add_pcic(). However I haven't fully grokked the meaning of the code which follows the request_region() in isa_probe(), so I'm not sure that the handling WRT multiple sockets and multiple bridge chips is correct. In particular I'm not convinced that the regions for subsequent sockets and/or bridges will be requested at all. I suspect a more thorough reworking by someone who understands what is going on there might be in order. I should mention that I'm actually messing about with this on an ARM platform with wacky memory and i/o mapping offsets etc, it doesn't quite work yet for other reasons which preclude full testing etc, but I think the problem above is still present for more normal x86 stuff.
