Subject: vsock: return errors other than -ENOMEM to socket
X-Git-Tag: v6.6.17~4755^2~179^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=02ab696febab622c4c837d509f6825884c952c22;p=platform%2Fkernel%2Flinux-rpi.git

vsock: return errors other than -ENOMEM to socket

This removes behaviour, where error code returned from any transport
was always switched to ENOMEM. This works in the same way as:
commit
c43170b7e157 ("vsock: return errors other than -ENOMEM to socket"),
but for receive calls.
