Subject: [PATCH 4.14 039/178] eeprom: at24: change nvmem stride to 1

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Lechner <david@...hnology.com>

commit 7f6d2ecd3d7acaf205ea7b3e96f9ffc55b92298b upstream.

Trying to read the MAC address from an eeprom that has an offset that
is not a multiple of 4 causes an error currently.

Fix it by changing the nvmem stride to 1.
