[ Upstream commit ad1abe476995d97bfe7546ea91bb4f3dcdfbf3ab ]

Deal with deferred probe using dev_err_probe so the error is handled
and avoid logging lots probe defer information like the following:

[    9.125121] cw2015 4-0062: Failed to register power supply
[    9.211131] cw2015 4-0062: Failed to register power supply
