This file contains ambiguous Unicode characters

This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

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.
