A fix is available — apply it.

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

dmaengine: ti: k3-udma-glue: Drop skip_fdq argument from k3_udma_glue_reset_rx_chn

The user of k3_udma_glue_reset_rx_chn() e.g. ti_am65_cpsw_nuss can run on multiple platforms having different DMA architectures. On some platforms there can be one FDQ for all flows in the RX channel while for others there is a separate FDQ for each flow in the RX channel.

So far we have been relying on the skip_fdq argument of k3_udma_glue_reset_rx_chn().

Instead of relying on the user to provide this information, infer it based on DMA architecture during k3_udma_glue_request_rx_chn() and save it in an internal flag 'single_fdq'. Use that flag at k3_udma_glue_reset_rx_chn() to deicide if the FDQ needs to be cleared for every flow or just for flow 0.

Fixes the below issue on ti_am65_cpsw_nuss driver on AM62-SK.
