Hello,
I tried spatch command again with few other files and it ran
successfully. (with the same ret.cocci file I sent)
spatch --sp-file ret.cocci --no-includes
~/git/kernels/staging/drivers/staging/sm750fb/ddk750_chip.c > ret.out
init_defs_builtins: /usr/lib64/coccinelle/standard.h
HANDLING:

But nothing with dim2_sysfs.c file and even ret.out file is empty. But
no errors this time.

Does coccinelle need driver to be compiled as a module? As hdm_dim2
driver is not but sm750fb driver is compiled as a module. Does coccinelle
require executable file to work?
Thanks,
Varsha
