Subject: [PATCH] dmadev: fix potential null pointer access
|
|
|
|
[ upstream commit e5389d427ec43ab805d0a1caed89b63656fd7fde ]
|
|
|
|
When rte_dma_vchan_status(dev_id, vchan, NULL) is called, a null pointer
|
|
access is triggered.
|
|
This patch adds the null pointer checker.
|
|
|
|
Fixes: 5e0f85912754 ("dmadev: add channel status check for testing use")
