This happens when trying to compile memory stick support inside the kernel.

drivers/memstick/core/mspro_block.o: In function `memstick_priv':
mspro_block.c:(.text+0x0): multiple definition of `memstick_priv'
drivers/memstick/core/memstick.o:memstick.c:(.text+0x0): first defined here
drivers/memstick/core/mspro_block.o: In function `memstick_get_drvdata':
mspro_block.c:(.text+0x6): multiple definition of `memstick_get_drvdata'
drivers/memstick/core/memstick.o:memstick.c:(.text+0x6): first defined here
drivers/memstick/core/mspro_block.o: In function `memstick_set_drvdata':
mspro_block.c:(.text+0xd): multiple definition of `memstick_set_drvdata'
drivers/memstick/core/memstick.o:memstick.c:(.text+0xd): first defined here 

This is because those three functions are not defined as static in "include/linux/memstick.h".
