Description
A vulnerability in the Linux kernel's dmaengine subsystem related to the ti k3-udma-glue driver was fixed by removing the skip_fdq argument from the k3_udma_glue_reset_rx_chn function. The fix involves inferring DMA architecture internally rather than relying on user input, preventing incorrect handling of flow descriptor queues (FDQs) on different platforms. This resolves a kernel warning and potential instability observed on the ti_am65_cpsw_nuss driver on AM62-SK hardware.
