[PATCH V2 0/3] soc: ti: Fix crash in error path when DMA channel open fails

[Nishanth Menon <nm@ti.com>]

Hi,

This is a respin of V1 of the series, to address a crash seen in
kernelci.org automated testing[1].

Changes in V2:
- Took Simon's suggestion in refactoring code to make
  knav_dma_open_channel return NULL and fix the callers accordingly.

Since the series does have inter-dependencies, I suggest the full series
could either go via net tree OR via SoC tree (if net maintainers dont
mind acking it). Personally, I have no issues of getting it via the net
tree.

I dropped the fixes tag here, any better suggestion to hit stable will
be nice to know, since the code is refactored a bit here.

V1: https://lore.kernel.org/all/20250926150853.2907028-1-nm@ti.com/
