[PATCH v2 08/10] wifi: atmel: remove unused ioctl function

From: Arnd Bergmann
Date: Wed Oct 11 2023 - 10:03:43 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

This function has no callers, and for the past 20 years, the request_firmware
interface has been in place instead of the custom firmware loader.

Acked-by: Kalle Valo <kvalo@xxxxxxxxxx>
