Solving checkpatch error with lex

[karthik nayak]

Hello,
was trying to fix the checkpatch error of not using c99 comments in the 
file
drivers/staging/rtl8192u/r8192U_dm.c
so I wrote a lex program to do so since there were way too many to do it 
manually.
Could anyone have a look at my lex code and tell me if I need to change it.
I have attached the lex code.
As per my testing it works perfectly, would love a second opinion.
Thanks,
Karthik
