    Subject[PATCH v2 0/9] eeprom: at24: at24cs series serial number read
    Date
    Chips from the at24cs EEPROM series have an additional read-only memory area
    containing a factory pre-programmed serial number. In order to access it, a
    dummy write must be executed before reading the serial number bytes.

    This series adds support for reading the serial number through a sysfs
    attribute.

    While we're at it: some of the patches contain readability tweaks and code
    organization fixes.

    Tested with at24cs64 and at24cs02 chips (for both 16 and 8 bit address
    pointers).

    v2:
    - protect the serial number read with a mutex

    v1: https://lkml.org/lkml/2015/10/20/162
