From afcd666d9db0ebfbf2751cce1e07b548547ca82e Mon Sep 17 00:00:00 2001 From: Wadim Egorov Date: Mon, 25 Apr 2016 15:20:43 +0200 Subject: [PATCH] regulator: rk808: remove linear range definitions with a single range The driver was using only linear ranges. Now we remove linear range definitions with a single range. So we have to add an ops struct for ranges and adjust all other ops functions accordingly.
