No I did:

make -C /home/vasya/linux drivers/staging/ft1000/ft1000-pcmcia/ft1000_hw.o
make: Вход в каталог `/home/vasya/dev/linux-next'
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CC      drivers/staging/ft1000/ft1000-pcmcia/ft1000_hw.o
drivers/staging/ft1000/ft1000-pcmcia/ft1000_hw.c: In function ‘ft1000_reset_card’:
drivers/staging/ft1000/ft1000-pcmcia/ft1000_hw.c:525: warning: passing argument 2 of ‘card_download’ discards qualifiers from pointer target type
drivers/staging/ft1000/ft1000-pcmcia/ft1000_hw.c:56: note: expected ‘void *’ but argument is of type ‘const u8 * const’
make: Выход из каталога `/home/vasya/dev/linux-next'

However, 

    cd ../drivers/staging/ft1000/ft1000-pcmcia/
    LANG=C make -C ~/linux ft1000_hw.o
    make: Entering directory `/home/vasya/dev/linux-next'
    make: *** No rule to make target `ft1000_hw.o'.  Stop.
    make: Leaving directory `/home/vasya/dev/linux-next'


Is "make" from linux root buggy/not supported for staging/everything?
