xhci: Remove some unnecessary casts and tidy some endian swap code
Some of the recently-added cpu_to_leXX and leXX_to_cpu made things somewhat messy; this patch neatens some of these areas, removing unnecessary casts in those parts also. In some places (where Y & Z are constants) a comparison of (leXX_to_cpu(X) & Y) == Z has been replaced with (X & cpu_to_leXX(Y)) == cpu_to_leXX(Z). The endian reversal of the constants should wash out at compile time. Signed-off-by: Matt Evans <matt@ozlabs.org> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
