arch/m68k/include/asm/hardirq.h:23:20: error: expected ')' before 'DRIVER_NAME'
make[4]: *** [drivers/memstick/core/ms_block.o] Error 1

The reason for this is that pr_fmt() references DRIVER_NAME and is defined
before the first include, while DRIVER_NAME is only defined in ms_block.h,
which is the last included file. If any subsequent include file uses pr_fmt()
(e.g. the call to pr_crit() in arch/m68k/include/asm/hardirq.h), this
causes a build
failure.

I suggest moving the DRIVER_NAME define to ms_block.c.
Cfr. memstick.c and mspro_block.c, who already have their own definition.
