Subject: [PATCH] staging: kpc2000: double unlock in error handling in kpc_dma_transfer()
Date: Wed, 15 May 2019 09:52:46 +0000 [thread overview]
Message-ID: <20190515095246.GH3409@mwanda> (raw)
The goto err_descr_too_many; calls unlock_engine() so this unlocks
twice.
Fixes: 7df95299b94a ("staging: kpc2000: Add DMA driver")
