Btw, you should update your test suite to prevent this kind of embarassing typo in the future. ;) Also I was reviewing enable_ints_write() earlier today and it does: ret = kstrtouint(buf, 10, &new_value); if (ret != 0) return ret; Don't do the "!= 0", it's a double negative and it doesn't contribute anything. Just do "if (ret) ". regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
