Subject: drivers: dma: ti: k3-udma: Extract packet data only when Meta data is not NULL
X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=a3f25b925fe690be7744d47df0135321e43e2c2a;p=u-boot.git

drivers: dma: ti: k3-udma: Extract packet data only when Meta data is not NULL

Currently packet data is wrongly extracted when metadata is NULL.
Fix it and negate the if check.
