target/linux/generic/patches-3.0/000-upstream-fix-__packed.patch

   1 checkpatch.pl warns about using __attribute__((packed)) in kernel
   2 headers: "__packed is preferred over __attribute__((packed))". If one
   3 follows that advice it could cause problems in the exported header
   4 files, because the outside world doesn't know about this shortcut.

   6 For example busybox will fail to compile:
   7  CC      miscutils/ubi_attach_detach.o
   8  In file included from miscutils/ubi_attach_detach.c:27:0:
   9  /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’
  10  /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here
  11 ...
  12
  13 Fix the problem by substituting __packed with __attribute__((packed)) in
  14 the header_install.pl script.
