Probelm on (brcmfmac: use pre-allocated scatter-gather table for txglomming)

Probelm on (brcmfmac: use pre-allocated scatter-gather table for txglomming)

[Michael Trimarchi]

Hi

I have a kernel panic on the brcmf_sdiod_sgtable_alloc just because
the function is called before brcmf_sdio_probe.

I think that
 nents = max_t(uint, BRCMF_DEFAULT_RXGLOM_SIZE,
                      sdiodev->bus_if->drvr->settings->sdiod_txglomsz);

drvr is null. Can you explain how it can work or do you have already a
fix for this?

Michael

What kernel version are you using? This has been fixed already in
4.5-rc2 or rc3.

Ok, I see it I was using rockchip for-next and I have seen now the fix

It sounds familiar so what kernel version are you seeing this.
