| Subject: power: supply: ab8500_charger: Fix an error handling path |
| |
| 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. |
| |
