+checkpatch.pl warns about using __attribute__((packed)) in kernel
+headers: "__packed is preferred over __attribute__((packed))". If one
+follows that advice it could cause problems in the exported header
+files, because the outside world doesn't know about this shortcut.
+
+For example busybox will fail to compile:
+ CC      miscutils/ubi_attach_detach.o
+ In file included from miscutils/ubi_attach_detach.c:27:0:
+ /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’
+ /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here
+...
+
+Fix the problem by substituting __packed with __attribute__((packed)) in
+the header_install.pl script.
