Hello Team,
I'm trying to make a commit to a checkpatch fix , and i have followed the instructions in the first patch tutorial but i'm not able to commit .
Following were the steps done .
1)Made changes to the file 

2)Run git diff command got the below output 

diff --git a/drivers/staging/comedi/comedi_fops.c b/drivers/staging/comedi/comedi_fops.c
index 146ab00..02a41bc 100644
--- a/drivers/staging/comedi/comedi_fops.c
+++ b/drivers/staging/comedi/comedi_fops.c

3) when i run git commit -a? i get the below message and the same goes for git commit -s -v
