[PATCH v2 0/2] cdrom: gdrom: fix block I/O and capacity setting

Hi all,

This series fixes a gdrom driver Oops due to bad MMIO register access and
fixes the missing updates of the block layer gendisk capacity that
prevented ISO9660 mounts from working.

The change was tested on real Sega Dreamcast devices (PAL-E, NTSC-J,
NTSC-U) with physical CD-R discs and with GDEMU emulated discs. Before:
Oops on mount and an unusable drive. After: Successfully able to mount
and use the inserted medium.

Thanks,
Florian

v1->v2: for "cdrom: gdrom: replace port I/O with MMIO accessors": Don't
	use helper functions with io.*_rep(), but writesw() and readsw()
	local in the respective functions. Improved failure case of
	gdrom_update_capacity() in gdrom_bdops_open().
