make /proc/acpi/ac_adapter dependent on ACPI_PROCFS
Do not provide /proc/acpi/ac_adapter if ACPI_PROCFS is not defined. This eliminates duplicated power adapters in HAL and makes it consistent with battery module Signed-off-by: Andrey Borzenkov <arvidjaar@mail.ru> Acked-by: Alexey Starikovskiy <astarikovskiy@suse.de> Cc: Len Brown <lenb@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
