Commit ae74ea64ccdb8b99ee2618b58020263d5b1d9b22 ("clk: at91: usb:
propagate rate modification to the parent clk") was a backport of a bug
fix applied in 4.0, but in the meantime the ->determine_rate() prototype
has changed, thus introduction a prototype mismatch bug in pre-4.0
kernels. This prototype mismatch was supposed to be fixed by commit
76723e7ed589998384a080e29204df4659c67cf2, which fix the bug on 3.19 kernels,
but the ->determine_rate() has also changed between 3.18 and 3.19.
Hopefully this patch will definitely fix the prototype mismatch for 3.18.
