This fixes a race between power supply device and initial attributes creation, plus makes it possible to implement writable properties. [Daniel Mack - removed superflous return statement and dropped .mode attribute from POWER_SUPPLY_ATTR] Suggested-by: Greg KH <gregkh@suse.de> Suggested-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com> Tested-by: Daniel Mack <daniel@caiaq.de>
