[PATCH 0/2] clk: fix a bug in CCF which results in a clock being enabled twice.

[Yang Xiwen via B4 Relay]

Currently, ccf_clk_endisable() calls clk_enable() / clk_disable()
directly depending on the request. However, this function is also
referenced in clk->ops, which is also called in clk_enable() /
clk_disable().

This caused a recursion and made the clock enabled twice if clk_enable()
is invoked. So we have to call clk_disable() twice to disable the clock.
It can be easily reproduced with few extra lines of debug code.

Fix that by calling clk->ops->enable/disable directly in
ccf_clk_endisable() rather than using the framework functions.
