o kill blank line that I introduced in cardinfo.h
o Delete unused variable wasinactive.
o return 0 from pccard_resume.
o Set the state and lastsate initially to be empty.
o move comment above code for interrupt dispatching.
o Powerstate interface is now available as of 430002, not 500000 (note that
this change will be not 100% correct since the power state stuff didn't
enter current until well after 500000, but it is good enough for the two
branche we have going now).
