Subject[PATCH 4.14 166/496] nbd: fix return value in error handling path
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Gustavo A. R. Silva" <gustavo@embeddedor.com>

[ Upstream commit 0979962f5490abe75b3e2befb07a564fa0cf631b ]

It seems that the proper value to return in this particular case is the
one contained into variable new_index instead of ret.
