Changes in v2 from the cover letter
- Add COMPILE_TEST for Kconfig option dependency.
- Drop warning message for unsupported SMBus transfer, since the driver will fall back to emulate them via I2C anyway.
- Kill ZX2967_I2C_FUNCS define by returning I2C_FUNC_XXX directly.
- Drop error message for i2c_add_numbered_adapter() check, since the core will do the reporting.
- Drop the error checking from zx2967_i2c_reset_hardware() which is useless now, and add it into irq handler for proper NACK handling.
