Subject: [PATCH] blobmsg: fix wrong payload len passed from
|
|
blobmsg_check_array
|
|
|
|
Fix incorrect use of blobmsg_len() on passed blobmsg to
|
|
blobmsg_check_array_len() introduced in commit 379cd33d1992
|
|
("fix wrong payload len passed from blobmsg_check_array") by using correct
|
|
blob_len().
|
|
|
|
By using blobmsg_len() a value too small was passed to blobmsg_check_array()
|
|
which could lead to this function returning an error when there is none.
