Hi, silverstri
how does it actually call 'spare'? Do I need to modify my Makefile to add a new target or something? If you called 'make C=2 ... ', the make will auto call sparse to check the source. Obviously, you should install sparse first.
If you do the 'make C=2 drivers/staging/wlan-ng/', and don't get the check results, I think maybe the 'wlan-ng' doesn't include in your built target. Please use 'make menuconfig' to add the target wlan-ng. 1. make menuconfig 2. select 'Device Drivers -->' 3. select 'Staging drivers -->' 4. select 'Prism2.5/3 USB driver' like this ' <M> Prism2.5/3 USB driver' 5. exit the menuconfig 6. make C=2 drivers/staging/wlan-ng/ then you will get the check result. I had test it on kernel v2.6.32.61, and got the messages below: ================================================ CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 CALL scripts/checksyscalls.sh CHECK scripts/mod/empty.c CHECK drivers/staging/wlan-ng/prism2usb.c drivers/staging/wlan-ng/hfa384x_usb.c:2810:62: warning: dubious: !x | !y drivers/staging/wlan-ng/prism2fw.c:124:14: warning: symbol 'ns3data' was not declared.

I am trying to use sparse to check my driver that I developed.
From http://kernelnewbies.org/Sparse, It said 'make C=2 drivers/staging/wlan-ng/', what does it check it I do 'make C=2' and how does it actually call 'spare'? Do I need to modify my Makefile to add a new target or something?
Thank you.
