Following Checkpatch, I thought it might be good to do as checkpatch said, but the code looks better and more readable without the change. This is my first patch and also a lesson that i should not fix every checkpatch warnings. I'll pick something better next time Thanks for your comment . ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
