question about arch/powerpc/platforms/cell/celleb_scc_uhc.c

The file arch/powerpc/platforms/cell/celleb_scc_uhc.c contains the
following function:
static inline int uhc_clkctrl_ready(u32 val)
{
const u32 mask = SCC_UHC_USBCEN | SCC_UHC_USBCEN;
return((val & mask) == mask);
}
The variable mask is a bit or of two identical constants. Later in the
same file in the function enable_scc_uhc, I see the code:
val |= (SCC_UHC_USBCEN | SCC_UHC_USBEN);
Should the code in uhc_clkctrl_ready also be SCC_UHC_USBCEN | SCC_UHC_USBEN?
Or something else?
thanks,
julia
