Author: dim Date: Sun Sep 4 16:59:35 2016 New Revision: 305388 URL: https://svnweb.freebsd.org/changeset/base/305388 Log: With clang 3.9.0, compiling uplcom results in the following warnings: sys/dev/usb/serial/uplcom.c:543:29: error: implicit conversion from 'int' to 'int8_t' (aka 'signed char') changes value from 192 to -64 [-Werror,-Wconstant-conversion] if (uplcom_pl2303_do(udev, UT_READ_VENDOR_DEVICE, UPLCOM_SET_REQUEST, 0x8484, 0, 1) ~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~~~~~~~~ sys/dev/usb/usb.h:179:53: note: expanded from macro 'UT_READ_VENDOR_DEVICE' #define UT_READ_VENDOR_DEVICE (UT_READ | UT_VENDOR | UT_DEVICE) ~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~ This is because UT_READ is 0x80, so the int8_t argument is wrapped to a negative value. Fix this by using uint8_t instead.
