The code in include/pcmcia/bulkmem.h was only kept for compatibility reasons. Therefore, move the remaining region_info_t definition to ds.h [linux@dominikbrodowski.net: do not modify the IOCTL, move definition to ds.h, and update changelog] Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
