+Subject: [PATCH 1/1] fix compilation issues with musl.
+
+- sys/time.h needed for struct timeval
+- unistd.h should not be included due to clash with encrypt(3)
+- sys/types.h needed for mode_t
+
+Note that this version of bluez is 3 years old. Recent fixes have gone
+into the upstream to address musl compatibility issues, but the upstream
+has changed so much that it makes little sense to try to backport these.
+This patch is really a stopgap until we move to the latest upstream.
+
+Upstream-Status: not needed
