Hi Alex,
There are two cases where this function still returns a pointer.
Around line 250:
ret = platform_get_irq_byname(ipa->pdev, "ipa");
if (ret <= 0) {
dev_err(dev, "DT error %d getting \"ipa\" IRQ property\n",
ret);
return ERR_PTR(ret ? : -EINVAL);
}
And around line 280:
return interrupt;
This does seem to be resolved in patch 2/7.
But as it is, this patch breaks bisection.
...
