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. Fixes: a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") Signed-off-by: Douglas Anderson <dianders@chromium.org> --- I'm not setup to actually test this, but I figured that I might as well go all the way and fix all the instances of the same pattern that I found in the ath drivers since the old call was actually breaking me in ath11k. I did at least confirm that the code compiles for me. If folks would rather not land an untested patch like this, though, feel free to drop this and just land patch #1 as long as that one looks OK.
