[PATCH net 0/2] net/stmmac: Secure against failures of DMA memory allocation

[Jakub Raczynski <j.raczynski@samsung.com>]

This series fixing two possible issues related to fails of
__alloc_dma_rx_desc_resources(). Original issue from 1st patch is related to
page_pool that has happened in testing env, while second was requested by
Sashiko to have similar change for DMA allocation. 
To have complete fix for all failures of __alloc_dma_rx_desc_resources(),
merge two fixes into series.

---
Note:
1st patch "Set Rx queue page_pool to NULL when freeing DMA resources" is
set to v2 while this series is v1. I know this is inconsistent, but this
series is not v2 and would be even more confusing.
Hopefully that doesn't break some CI, as second patch is v1.

Changes in v2 (in first patch):
- Added reviewed by Maxime
- Dropped null check as page_pool_destroy() does provide that
- Modified comment to reflect that

Jakub Raczynski (2):
  net/stmmac: Set Rx queue page_pool to NULL when freeing DMA resources
  net/stmmac: Prevent dma queue NULL free on allocation failure
