PM / Runtime: Move code in drivers/base/power/runtime.c
This patch (as1421) moves the PM runtime accounting subroutines up to the beginning of runtime.c, taking them out of the middle of the functions that do the actual work. No operational changes. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
