dmaengine: ti: k3-udma-glue: Drop skip_fdq argument from k3_udma_glue_reset_rx_chn
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. > ip link set eth1 down > ip link set eth0 down > ethtool -L eth0 rx 8 > ip link set eth0 up > modprobe -r ti_am65_cpsw_nuss [ 103.045726] ------------[ cut here ]------------ [ 103.050505] k3_knav_desc_pool size 512000 != avail 64000 [ 103.050703] WARNING: CPU: 1 PID: 450 at drivers/net/ethernet/ti/k3-cppi-desc-pool.c:33 k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool] [ 103.068810] Modules linked in: ti_am65_cpsw_nuss(-) k3_cppi_desc_pool snd_soc_hdmi_codec crct10dif_ce snd_soc_simple_card snd_soc_simple_card_utils display_connector rtc_ti_k3 k3_j72xx_bandgap tidss drm_client_lib snd_soc_davinci_mcas p drm_dma_h
