[PATCH] iwlwifi: mvm: Fix an error handling path in 'ebu_dma_start()'
From: Christophe JAILLET
Date: Sun Jan 24 2021 - 03:00:00 EST
If the 'cmd_ver' check fails, we must release some memory as already done
in all the other error handling paths of this function.
Fixes: 9e3c39361a30 ("iwlwifi: mvm: support new KEK KCK api")
