NULL pointer de-reference error was observed when all the PCIe endpoint functions (22 function in J721E) request a DMA channel. The issue was specfically observed in BCDMA (Block copy DMA) but the issue is applicable in PKTDMA as well.
Changes from v1: 1) Split the patch for BCDMA and PKTDMA separately 2) Fixed the return value of udma_get_rflow() to 0. 3) Removed the fixes tag as the patches does not directly apply to the commits.
v1 => https://lore.kernel.org/r/20210209090036.30832-1-kishon@ti.com
