Subject: clk: at91: fix clk-generated parenting
From: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxxxxxxxxx>
[ Upstream commit 8e56133e5c7b7a7a97f6a92d92f664d5ecd30745 ]
clk_generated_startup is called after clk_hw_register. So the first call to
get_parent will not have the correct value (i.e. 0) and because this is
cached, it may never be updated.
