The use of ifneq against 'n' to conditionally compile codec-specific parts is wrong and was resulting in all the codec tables being built even for deselected codecs.
For the WM5102 there is an extra dependency on wm5102_patch() so it is given an alternative empty version when deselected to avoid having to sprinkle #ifdefs around the code.
