From 424cfde49acaf1426e90837961e8aead0238b11b Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Tue, 22 Sep 2015 14:35:07 -0500 Subject: [PATCH] power: bq27xxx_battery: Platform initialization must declare a device When initialized as a platform device the initializer must now specify a device. An empty device name is no longer valid. Signed-off-by: Andrew F.
