[RESEND PATCH v2 0/9] eeprom: at24: at24cs series serial number read

[Bartosz Golaszewski]

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).

(rebased against 4.4-rc1)

v2:
- protect the serial number read with a mutex

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