From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit bf59fddde1c3eab89eb8dca8f3d3dc097887d2bb ]
'ret' is know to be 0 at this point, because it has not been updated by the the previous call to 'abx500_mask_and_set_register_interruptible()'.
Fix it by updating 'ret' before checking if an error occurred.
