+Subject: [PATCH] usbbus: Include stdint.h for uintX_t
+
+stdint.h is needed for uintX_t typedefs which are
+used to replace u_intX_t in libusb API headers in the cmake files
+
+Define _GNU_SOURCE since thats not defined by default for musl
+C library on linux
+
+Upstream-Status: Submitted [https://github.com/nfc-tools/libnfc/pull/544]
