Subject: [CONNECTOR]: Return proper error code in cn_call_callback()
X-Git-Tag: v2.6.24-rc7~6^2~2
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=134d99e302618eeb102c2a5be1f9e98696288bdd;p=~shefty%2Frdma-dev.git

[CONNECTOR]: Return proper error code in cn_call_callback()

Error code should be set to EINVAL instead of ENODEV if !queue_work().
There's another call of queue_work() which may set err to EINVAL.
