what you said about C code warning whether is follows ? If is it, and I 
had add a static for loongson2_thermal_remove in v3 version code, I
think it shoud be fixed  about the warning.
 >> drivers/thermal/loongson2_thermal.c:183:5: warning: no previous 
prototype for function 'loongson2_thermal_remove' [-Wmissing-prototypes]
    int loongson2_thermal_remove(struct platform_device *pdev)
        ^
    drivers/thermal/loongson2_thermal.c:183:1: note: declare 'static' if 
the function is not intended to be used outside of this translation unit
    int loongson2_thermal_remove(struct platform_device *pdev)
    ^
    static
    1 warning generated.

If you said about C code warning isn't about about 
"loongson2_thermal_remove" and I may be loss a mail about that C code 
warning, Could you foward a mail about that C code warning. because I 
don't find any C code warning when compile C code.

About the C code warning, it was base on v6 code?
