Hello,

    Thanks Julia and Vaishali for helping me. I understood the reason for 
blank output. 
    Since, the *file has already been updated with the coccinelle output 
patch and 
    as Vaishali said, so there is no case where coccinelle can be applied.
    Probably the example needs to be changed, as it may create confusion 
for newbies.

    Thanks,
    Varsha

    *File referred here is most/hdm-dim2/dim2_sysfs.c
