Converting to an rbtree cache as regcache doesn't have a flat cache. Since the top of the register map is fairly sparse this should be an overall win.

+static bool wm8903_readable_register(struct device *dev, unsigned int reg) +{

• switch (reg) {
• case WM8903_FLL_CONTROL_1:
• case WM8903_FLL_CONTROL_2:
• case WM8903_FLL_CONTROL_3:
• case WM8903_FLL_CONTROL_4:
