[PATCH AUTOSEL 5.3 33/89] RDMA/core: Fix an error handling path in 'res_get_common_doit()'

From: Sasha Levin
Date: Fri Oct 18 2019 - 18:26:58 EST


From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit ab59ca3eb4e7059727df85eee68bda169d26c8f8 ]

According to surrounding error paths, it is likely that 'goto err_get;' is
expected here. Otherwise, a call to 'rdma_restrack_put(res);' would be
missing.

Fixes: c5dfe0ea6ffa ("RDMA/nldev: Add resource tracker doit callback")
