See http://www.infradead.org/rpr.html Precedence: bulk List-ID: au1xmmc is split somewhat awkwardly into the main mmc subsystem driver, and callbacks in platform_data that sit under arch/mips/ and are always built in. The latter than call mmc_detect_change through symbol_get. Remove the use of symbol_get by requiring the driver to be built in. In the future the interrupt handlers for card insert/eject detection should probably be moved into the main driver, and which point it can be built modular again.
