From 8e2f5eae24351d6f536c602eccdc4ad12b675c28 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 12 Apr 2019 14:36:36 +0200 Subject: [PATCH] usb: ohci-da8xx: let the regulator framework keep track of use count There's no reason to have a separate variable to keep track of the regulator state. The regulator core already does that. Remove reg_enabled from struct da8xx_ohci_hcd.
