It can be an issue when someone using x out of the range. It can be done via build time checking. https://elixir.bootlin.com/linux/latest/source/include/linux/build_bug.h#L49 Normally we wouldn't bother and would rely on review to pick up on this but I'd have no problem with a paranoid check in the macro. Particularly as 28 isn't exactly and obvious number to support! > > Thanks > Xiang > > > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_1 0x200544 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_2 0x200545 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_3 0x200546 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_4 0x200547 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_5 0x200548 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_6 0x200549 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_7 0x20054A > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_8 0x20054B > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_9 0x20054C > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_10 0x20054D > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_11 0x20054E > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_12 0x20054F > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_13 0x200550 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_14 0x200551 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_15 0x200552 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_16 0x200553 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_17 0x200554 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_18 0x200555 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_19 0x200556 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_20 0x200557 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_21 0x200558 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_22 0x200559 > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_23 0x20055A > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_24 0x20055B > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_25 0x20055C > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_26 0x20055D > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_27 0x20055E > > > +#define HID_USAGE_SENSOR_DATA_FIELD_CUSTOM_VALUE_28 0x20055F > > > + > > > #endif > >
