regulator: Ensure enough enable time for max8649
Integer division may truncate the result, thus max8649_enable_time() may return slightly shorter enable time. This patch fixes it. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
