[PATCH v2 1/2] mfd: arizona: Add stub for wm5102_patch()

[PATCH v2 1/2] mfd: arizona: Add stub for wm5102_patch()

[Richard Fitzgerald]

For the WM5102 there is a dependency in the core code on wm5102_patch()
which only exists when CONFIG_MFD_WM5102 is defined. To avoid having
to sprinkle #ifdefs around the code it is given an alternative empty
stub version when CONFIG_MFD_WM5102 is deselected

[PATCH v2 2/2] mfd: arizona: Fix incorrect Makefile conditionals

[Richard Fitzgerald]

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.
