The sub function takes a void *, then passes it directly to clk_disable_unprepare(), which handles the more specific type. Reported by clang when building with warnings enabled: drivers/pci/controller/dwc/pcie-keembay.c:172:12: warning: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Wcast-function-type-strict] (void(*)(void *))clk_disable_unprepare, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ No functional changes are intended.
