4.14-stable review patch. If anyone has any objections, please let me know.
Hi Greg,
this looks like a new feature, not a fix. Are you sure this should go into the stable branch?
Best regards, Bartosz Golaszewski
[ Upstream commit a2b3bf4846e5eed62ea6abb096af2c950961033c ]
Provide a flexible way to determine the addressing bits of eeprom. Pass the addressing bits to driver through address-width property.
