Remove unnecessary includes from base.h. Add includes to other files as necessary. Don't include base.h unless needed. Move declarations for functions in base.c from ath5k.h to base.h. Use a better named define to protect base.h against double inclusion. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
