    iio: st_sensors: add devicetree probing support · 2d7768a8
    Linus Walleij authored
    The I2C devices that make up the STMicroelectronics MEMS sensors
    may be sneakily enabled by cleverly giving the device node the same
    name as a string match from the platform device ID table. However
    the right method is to use the compatible string.
    
    On detection, the ST sensors use the ID string to probe and
    instatiate the right sensor driver, so pass the kernel-internal ID
    string in the .data field of the OF match table, and set the I2C
    client name to this name when a compatible match is used.
    
    This avoids having misc Linux-specific strings floating around in
    the device tree.
