From 625faa6a720d26fc0db9e20b48dc0dfe4c8d8ddf Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 20 Oct 2015 11:49:44 +0100 Subject: clkdev: fix clk_add_alias() with a NULL alias device name clk_add_alias() was not correctly handling the case where alias_dev_name was NULL: rather than producing an entry with a NULL dev_id pointer, it would produce a device name of (null). Fix this.
