From 09edcb647542487864e23aa8d2ef26be3e08978a Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Wed, 22 Nov 2017 21:31:20 +0100 Subject: [PATCH] power: supply: ab8500_charger: Bail out in case of error in 'ab8500_charger_init_hw_registers()' If an error occurs when we enable the backup battery charging, we should go through the error handling path directly. Before commit db43e6c473b5 ("ab8500-bm: Add usb power path support") this was the case, but this commit has added some code between the last test and the 'out' label. So, in case of error, this added code is executed and the error may be silently ignored. Fix it by adding the missing 'goto out', as done in all other error handling paths.
