From 71e5770b618a2a10d9f92eade0ea0f2c8aaca58d Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 9 Jun 2020 14:23:18 +0200 Subject: sd/pxa2xx_mmci: Fix to realize "pxa2xx-mmci" device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit pxa2xx_mmci_init() creates a "pxa2xx-mmci" device, but neglects to realize it. Affects machines akita, borzoi, connex, mainstone, spitz, terrier, tosa, verdex, and z2. In theory, a device becomes real only on realize. In practice, the transition from unreal to real is a fuzzy one. The work to make a device real can be spread between realize methods (fine), instance_init methods (wrong), and board code wiring up the device (fine as long as it effectively happens on realize). Depending on what exactly is done where, a device can work even when we neglect to realize it. This one appears to work. Nevertheless, it's a clear misuse of the interface. Even when it works today (more or less by chance), it can break tomorrow. Fix by realizing it right away.
