From: Arnd Bergmann
Date: Fri Mar 14 2025 - 11:48:32 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
Without this, the driver fails to build:
ld: drivers/firmware/thead,th1520-aon.o: in function `th1520_aon_call_rpc':
thead,th1520-aon.c:(.text+0x28): undefined reference to `mbox_send_message'
ld: drivers/firmware/thead,th1520-aon.o: in function `th1520_aon_deinit':
thead,th1520-aon.c:(.text+0x17e): undefined reference to `mbox_free_channel'
ld: drivers/firmware/thead,th1520-aon.o: in function `th1520_aon_init':
thead,th1520-aon.c:(.text+0x1d9): undefined reference to `mbox_request_channel_byname'
Fixes: e4b3cbd840e5 ("firmware: thead: Add AON firmware protocol driver")
