* bmp280
   - Fix wrong relative humidity unit.
 * buffer
   - Fix a function signature to match the function.
 * inv_mpu6050
   - Fix a regression in which older ACPI devices won't have working
     interrupts due to lack of information on the interrupt type.
 * mma8452
   - Don't ignore data ready interrupt when handling interrupts as will
     look like an unhandled interrupt.
 * tsl2x7x/tsl2772
   - Avoid a potential division by zero.
