4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx>
commit 625faa6a720d26fc0db9e20b48dc0dfe4c8d8ddf upstream.
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.
Fixes: 2568999835d7 ("clkdev: add clkdev_create() helper")
