Subject: [PATCH 4.19 025/131] rocker: fix incorrect error handling in dma_rings_init
From: Aditya Pakki <pakki001@....edu>
[ Upstream commit 58d0c864e1a759a15c9df78f50ea5a5c32b3989e ]
In rocker_dma_rings_init, the goto blocks in case of errors
caused by the functions rocker_dma_cmd_ring_waits_alloc() and
rocker_dma_ring_create() are incorrect. The patch fixes the
order consistent with cleanup in rocker_dma_rings_fini().
