I am a newbie... just start recently preparing for the out reach program in 
December.... i started at: https://kernelnewbies.org/Outreachyfirstpatch 
but i have a number of difficulties:
1. After editx... ,  recompiling my driver, installing the changes and 
rebooting my linux system . I tested the changes but i didn't find the 
message " I can modify the Linux kernel!".... i contacted the irc 
channel:#kernel-outreachy but i seemed not to exist.
2. i went ahead to creating the .git/hooks/pre-commit but when i try 
staging and commiting the file i get the respective errors:

error: Invalid path '.git/hooks/pre-commit'
error: unable to add .git/hooks/pre-commit to index
fatal: adding files failed

and

error: pathspec 'First patch' did not match any file(s) known to git.

please some one help me out???

Hi Courage ? ;)
I'll help you.  I'm an outreachy intern now. 

We need to move this thread over to linux-newbie mailing list, since
this outreachy list won't be active until the next application round.
Please 'cc linux-newbie on posts as I've done above.

Let's go step by step. 

Let's make sure you put in a printk that will get printed.
Let's make sure you've compiled the module.

Confirm you compiled the module...do you see a .ko with new timestamp?

Can you sudo modprobe <drivername> ?
Or sudo insmod drivername.ko ?

(at this point you don't need to keep rebooting the kernel.  We will
modprobe add/remove your driver.)

post what you have on the above items and I'll take a look.

You are not submitted that pre-commit hooks file.  It lives in your
git tree to poke you went you make a submittal.

Thanks for the reply. 
I did run the command but no output. i got an idea but i don't know if its 
right
i actually edited but the diver file in a folder in my work directory  not 
the driver file in my OS 
kernel...:/home/courage/git/kernels/staging/drivers/net/ethernet/intel/e1000


while the r other instances of this driver in my computer:
/lib/modules/3.13.0-32-generic/kernel/drivers/net/ethernet/intel/e1000
/lib/modules/4.7.0-rc6+/kernel/drivers/net/ethernet/intel/e1000

OOPS!!!  I just reaquainted myself with the first patch tutorial and
realize that you are on the step that tells you to modify a driver
that is running on your system. So - forget what I said about modprobe
and insmod.  You'll do that in the next step.  (It wouldn't hurt your
system, it just would fail with device busy.)

OK...see more below

here's what i'd do on my system, see if you can track similar.

Find which ethernet modules sys is using:
$ lsmod | grep e1000
e1000e                233472  0 
ptp                    20480  1 e1000e

Go find it:

amsfield22@d830:~/git/kernels/iio/drivers/net/ethernet/intel$ ls
e1000   e100.c  i40e    igb    ixgb   ixgbevf  Makefile
e1000e  fm10k   i40evf  igbvf  ixgbe  Kconfig
amsfield22@d830:~/git/kernels/iio/drivers/net/ethernet/intel$ cd e1000e
amsfield22@d830:~/git/kernels/iio/drivers/net/ethernet/intel/e1000e$ ls
80003es2lan.c  defines.h  ich8lan.c  Makefile  nvm.c    phy.h
80003es2lan.h  e1000.h    ich8lan.h  manage.c  nvm.h    ptp.c
82571.c        ethtool.c  mac.c      manage.h  param.c  regs.h
82571.h        hw.h       mac.h      netdev.c  phy.c
amsfield22@d830:~/git/kernels/iio/drivers/net/ethernet/intel/e1000e$
grep probe *.c
netdev.c: * e1000_probe - Device Initialization Routine
netdev.c: * e1000_probe initializes an adapter identified by a pci_dev
structure.
netdev.c:static int e1000_probe(struct pci_dev *pdev, const struct
pci_device_id *ent)
netdev.c:	.probe    = e1000_probe,
amsfield22@d830:~/git/kernels/iio/drivers/net/ethernet/intel/e1000e$ 

I'd edit the probe function in netdev.c

Then follow tutorial instructions for rebuild/reboot.
Look in dmesg for your printk message.

Let me know if you get further along...

note: my tree is called 'iio' while you've named yours 'staging' of
course.  And, yes, you need to be doing the changes and building in
your git staging tree.

kernelnewbies.org, i then ran the following:
1.make 'make drivers/net/ethernet/intel/e1000/
2.sudo make install drivers/net/ethernet/intel/e1000/

On rebooting I got FATAL: Could not load 
/lib/modules/4.5.0-rc3+/modules.dep: No such file or directory.
Is there somewhere that I might be going wrong?
Did your steps differ from mine? If yes, please let me know what you did 
differently.
Thanks!
