This was already fixed in several other Atheros WiFi drivers, apparently in response to Zeal Robot reports. An example of another fix is commit 9503a1fc123d ("ath9k: Use platform_get_irq() to get the interrupt"). ath11k seems to have been missed in this effort, though. Without this change, WiFi wasn't coming up on my Qualcomm sc7280-based hardware. Specifically, "platform_get_resource(pdev, IORESOURCE_IRQ, i)" was failing even for i=0.
