Priority P4 17

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: thunderbay: fix possible memory leak in thunderbay_build_functions()

The thunderbay_add_functions() will free memory of thunderbay_funcs
when everything is ok, but thunderbay_funcs will not be freed when
thunderbay_add_functions() fails, then there will be a memory leak,
so we need to add kfree() when thunderbay_add_functions() fails to
fix it.

In addition, doing some cleaner works, moving kfree(funcs) from
thunderbay_add_functions() to thunderbay_build_functions().
