Subject: [PATCH v2] memstick: make enable_dma less generic in r592

Fixes this build error:

drivers/memstick/host/r592.c:26: error: 'enable_dma' redeclared as different kind of symbol
arch/powerpc/include/asm/dma.h:189: note: previous definition of 'enable_dma' was here

v2: get the arguments to module_param_named() in the right order (blush :-))

This has been applied to linux-next today.
