CVE-2026-98416

dmaengine: ti: k3-udma-glue: fix NULL dereference in k3_udma_glue_release_rx_chn()

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: ti: k3-udma-glue: fix NULL dereference in k3_udma_glue_release_rx_chn()

If devm_kcalloc() for rx_chn->flows fails in a channel request function,
the error path calls k3_udma_glue_release_rx_chn(), which dereferences
the NULL rx_chn->flows pointer in k3_udma_glue_release_rx_flow().

Skip the flow release loop in k3_udma_glue_release_rx_chn() when
rx_chn->flows is not allocated.
