[PATCH] clk: Register clkdev after setup of fixed-rate and fixed-factor clocks

From: Orson Zhai
Date: Tue Oct 11 2016 - 07:43:36 EST


From: Xiaolong Zhang <xiaolong.zhang@xxxxxxxxxxxxxx>

When common kernel setups fixed clock, of_clk_provider will be registerred.
But there is no clkdev being registerred at the same time. This will make
it difficult to get the clock by using clk_get(NULL, con_id).

Add clkdev register for fixed-rate and fixed-factor clock and ignore
the error if any.
