+Subject: [PATCH] libmtd: compile fix for linux header changes.
+
+In the Linux kernel source, mtd/mtd-user.h had a change
+'mtd: mtd-user: remove stdint.h include'
+(137d36af4a53858b8db7ca83c8480247118b8bdf)
+
+This causes the uint8_t/uint64_t types to be undefined in libmtd.h
+now, as they were implicitly coming from it before.
+
+Import stdint.h explicitly into libmtd.h to resolve this.

As you recent changed this package, you probably can spot problems on my patch more easily than others ;-) Unfortunately I was not able to understand why in some conditions the build works.
