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.

/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.
