Subject: mmc: au1xmmc: force non-modular build and remove symbol_get usage
From: Christoph Hellwig <hch@xxxxxx>
commit d4a5c59a955bba96b273ec1a5885bada24c56979 upstream.
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.
