From 1f5163fcf1523e2890d3e8909daed777661765ab Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 6 Dec 2018 13:43:49 +0100 Subject: [PATCH] regulator: s5m8767: Hand over GPIO to regulator core The GPIO descriptors used by the S5M8767 driver are retrieved during probe() and it is really helpful to have those under devres management because of all the errorpaths in the intialization. Using the new dev_gpiod_unhinge() call we can remove the devres management of the descriptor right before handing it over to the regulators core.
