Why is this a global?
Normally, this should be an element in the structure, but since there is
only one

element, It is directly defined as a global variable for use by other
function.

Ok. Globals are frowned upon but it's just a single pointers so I guess
it's Ok.

+ return PTR_ERR(loongson2_pll_base);
+
+ loongson2_clocks_init(dev);
Please inline this function here.
The loongson2_clocks_init had inline in this version, or do you mean something else ? Need to inline the probe?
I mean get rid of the function loongson2_clocks_init() and move the code
in that function into this probe function. With this patch the probe is
split to two functions when it should be one function.

okay, I got it.


Thanks.
