Subject: [PATCH] rocker: fix incorrect error handling in dma_rings_init
Date: Fri, 12 Jun 2020 15:27:55 -0500 [thread overview]
Message-ID: <20200612202755.57418-1-pakki001@umn.edu> (raw)
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().
