From 6105e9ab64c6dea7337a4c9bc996e0cdde59a799 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 17 Aug 2020 09:10:55 +0200 Subject: [PATCH] staging: regulator: hi6421v600-regulator: initialize ramp_delay Without that, the regulator's core complains with: ldo17: ramp_delay not set For now, use the enable time, as we don't have any datasheets from this device.
