[PATCH] pcmcia: rsrc_nonstatic: sysfs input
Add a sysfs input method for the non-static socket resource database. It
works by writing
"+ 0x%[l]x - 0x%[l]x"
or simply
"0x%[l]x - 0x%[l]x"
for adding resources, and by
"- 0x%[l]x - 0x%[l]x"
for removing resources to
/sys/class/pcmcia_socket/pcmcia_socket%n/available_resources_{io_mem}
