Subject: [PATCH] NTB: Fix static check warning in perf_clear_test
Git-commit: a0348a4da1a7073fa14065f370f507073b857782
Patch-mainline: v5.8-rc1
References: git-fixes
As pthr->dma_chan can't be NULL in this context, so there is
no need to check pthr->dma_chan.
Fixes: 99a06056124d ("NTB: ntb_perf: Fix address err in perf_copy_chunk")
