* Name: bmi270_register
*
* Description:
* Register the BMI270 character device as 'devpath'
*
* Input Parameters:
* devpath - The full path to the driver to register. E.g., "/dev/accel0"
* dev - An instance of the SPI or I2C interface to use to communicate
* with BMI270
* addr - (I2C only) I2C address
*
* Returned Value:
* Zero (OK) on success; a negated errno value on failure.
