Compiling a specific driver

Compiling a specific driver

I was wondering if anyone could explain the steps to be followed in order 
to make sure the driver I am working on is compiled
when running 'make -j5'. 

So far, I did the steps explained at [1], under the 'Recompiling the 
driver' section, but when selecting 'Staging drivers' the driver list is 
empty.

Thanks a lot.

If you are working on a specific driver, you can type something like this:

make drivers/staging/rtl8723au/r8723au.ko

I run the following command as you suggested:
      make drivers/staging/wlan-ng/wlan-ng.ko
but I get the output:
     CHK     include/config/kernel.release
     CHK     include/generated/uapi/linux/version.h
     CHK     include/generated/utsrelease.h
     CALL    scripts/checksyscalls.sh
     make[1]: *** No rule to make target
`drivers/staging/wlan-ng/wlan-ng.o'.  Stop.
     make: *** [drivers/staging/wlan-ng/wlan-ng.ko] Error 2

[jes@ultrasam jes.git]$ cat drivers/staging/wlan-ng/Makefile
obj-$(CONFIG_PRISM2_USB) += prism2_usb.o

prism2_usb-y := prism2usb.o \
		p80211conv.o \
		p80211req.o \
		p80211wep.o \
		p80211netdev.o

There is no wlan-ng.o object, try 'prism2_usb.ko'
