These 2 patches are needed to build udev with the 4.4 kernel, the first
mtd-probe adds back a stdint.h header that was removed in the kernel's mtd-user.h
header file.

The second adds a check for a new header and sets a Makefile variable
to determine which header to use for the new kernel vs older kernels.

+Subject: [PATCH 2/2] configure.ac/Makefile.am: Check for input.h and
+ input-event-codes.h
+
+Add INPUT_HEADER to know which header file to use because it changed
+in the 4.4 kernel code.
+
+Set INPUT_HEADER with default linux/input.h if it exists and if the
+newer input-events-codes.h exists from 4.4 use it instead.
