Subject: vsock/vmci: convert VMCI error code to -ENOMEM on send
X-Git-Tag: v6.6.17~5185^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ffa5395a7901e83a68d88207c4592962906641bd;p=platform%2Fkernel%2Flinux-rpi.git

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

This adds conversion of VMCI specific error code to general -ENOMEM. It
is needed, because af_vsock.c passes error value returned from transport
to the user, which does not expect to get VMCI_ERROR_* values.

Fixes: c43170b7e157 ("vsock: return errors other than -ENOMEM to socket")
