From 70f3ce0510afdad7cbaf27ab7ab961377205c782 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 29 Sep 2014 11:47:54 +0200 Subject: mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Drivers currently call spi_nor_match_id() and then spi_nor_scan(). This adds a dependency on struct spi_device_id which we want to avoid. Make spi_nor_scan() do it for them.

The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.
