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

From: Bartosz Golaszewski
Date: Tue Nov 17 2015 - 04:54:14 EST

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

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

(rebased against 4.4-rc1)

- protect the serial number read with a mutex
