Subject: [PATCH] bus-message: let's always use -EBADMSG when the message is
|
|
|
|
|
bad
|
|
|
|
|
|
|
|
|
|
-EINVAL means the arguments were somehow wrong, so translate the code we get
|
|
|
|
|
internally into -EBADMSG when returning.
|
|
|
|
|
|
|
|
|
|
(cherry picked from commit 69bd42ca072dfb2f7603b1f82053063293ab54b5)
