Damien Le Moal 777595da53 null_blk: Fix return value of nullb_device_power_store() ... commit d9ff882b54 upstream. When powering on a null_blk device that is not already on, the return value ret that is initialized to be count is reused to check the return value of null_add_dev(), leading to nullb_device_power_store() to return null_add_dev() return value (0 on success) instead of "count". So make sure to set ret to be equal to count when there are no errors.
