Subject: vsock/vmci: convert VMCI error code to -ENOMEM on receive
X-Git-Tag: v6.6.17~4755^2~179^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f59f3006ca7b2fc9bf38fbf44e3dc4b1fbd686c1;p=platform%2Fkernel%2Flinux-rpi.git

vsock/vmci: convert VMCI error code to -ENOMEM on receive

This adds conversion of VMCI specific error code to general -ENOMEM. It
is preparation for the next patch, which changes af_vsock.c behaviour
on receive to pass value returned from transport to the user.
