3.6.11.3 stable review patch. If anyone has any objections, please let me know.
------------------ From: David Woodhouse <[email protected]> [ Upstream commit f5cf8f07423b2677cebebcebc863af77223a4972 ] This code was broken because it assumed that all MTD devices were map-based. Disable it for now, until it can be fixed properly for the next merge window.
