We could leave it as is or change it to "MAX_WPA_IE_LEN - 1". But I feel like the default should be to leave it as is unless there is a good reason. So from a static analysis perspective we wouldn't complain unless/until the "n" is re-used outside the loop. So this a chance to make a smarter static analyzer. regards, dan carpenter _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
