[OpenWrt-Devel] ath10k fails to load firmware in r46386 on ESR1750

[Christian Beier]

Hi list!

On an EnGenius ESR1750 running current trunk (r46386), the ath10k driver fails
to load the firmware blob - it did work in Barrier Breaker though. Here's the
failing dmesg bits:

---snip---
[   72.050000] PCI: Enabling device 0000:00:00.0 (0000 -> 0002)

Barrier Breaker dmesg instead:
---snip---

Any hints on this?
