This sort of thing is done deliberately as a style choice... I probably wouldn't have written it that way myself, but there really isn't a downside to leaving it as-is. The unused "int ret = 0;" just introduces a static checker warning about unused assignments and disables the static checker warning for uninitialized variables so we want to remove that. regards, dan carpenter _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
