mfd: axp20x-i2c: Do not define 'struct acpi_device_id' when !CONFIG_ACPI
Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI, struct axp20x_i2c_acpi_match becomes defined by unused. This squashes the current W=1 kernel builds warning: drivers/mfd/axp20x-i2c.c:82:36: warning: ‘axp20x_i2c_acpi_match’ defined but not used [-Wunused-const-variable=] Cc: Chen-Yu Tsai <wens@csie.org> Cc: Carlo Caione <carlo@caione.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
