Subject: SUNRPC: return proper errno from backchannel_rqst
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d24bab93e42b1f90d89c86b3edbb81ec34bb9474;p=openwrt%2Fstaging%2Fblogic.git

SUNRPC: return proper errno from backchannel_rqst

The one and only caller (in fs/nfs/nfs4client.c) uses the result
as an errno and would have interpreted an error as EPERM.
