[ Upstream commit 95c95251d0547b46d6571e4fbd51b42865c15a4a ]
As of commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core"), we need to use platform_get_irq() instead of platform_get_resource() to get our IRQs because platform_get_resource() simply won't get them anymore.
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"). ath5k seems to have been missed in this effort, though.
