Henry Martin 643db430f4 dmaengine: ti: Add NULL check in udma_probe() 
[ Upstream commit fd447415e7 ]

devm_kasprintf() returns NULL when memory allocation fails. Currently,
udma_probe() does not check for this case, which results in a NULL
pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue.

Fixes: 25dcb5dd7b ("dmaengine: ti: New driver for K3 UDMA")
