From 1de3821ace8200432993821bfda043827029de2a Mon Sep 17 00:00:00 2001 From: Markus Pargmann Date: Mon, 3 Nov 2014 19:12:04 +0100 Subject: [PATCH] regulator: Set ena_gpio_initialized in regulator drivers This patch sets ena_gpio_initialized for all drivers which set a ena_gpio from parsed DT properties. Drivers using pdata may get zero initialized pdata and therefore copy a 0 into the regulator_config ena_gpio field.
