Subject: [PATCH] eeprom: at24: change nvmem stride to 1
Git-commit: 7f6d2ecd3d7acaf205ea7b3e96f9ffc55b92298b
Patch-mainline: v4.15-rc4
References: bsc#1051510

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.
