Subject: dma-buf: Adjust a null pointer check in dma_buf_attach()
X-Git-Tag: v4.13-rc1~73^2~30^2~28
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=34d84ec4881d1343bec8c0848fd946e3073e6612;p=thirdparty%2Fkernel%2Flinux.git

dma-buf: Adjust a null pointer check in dma_buf_attach()

The script "checkpatch.pl" pointed information out like the following.

Comparison to NULL could be written "!attach"

Thus adjust this expression.
