The wkup_m3_rproc_boot_thread() function uses a nonstandard prototype,
which broke after Eric's recent cleanup:
drivers/soc/ti/wkup_m3_ipc.c: In function 'wkup_m3_rproc_boot_thread':
drivers/soc/ti/wkup_m3_ipc.c:429:16: error: 'return' with a value, in function returning void [-Werror=return-type]
429 | return 0;
| ^
drivers/soc/ti/wkup_m3_ipc.c:416:13: note: declared here
416 | static void wkup_m3_rproc_boot_thread(struct wkup_m3_ipc *m3_ipc)
| ^~~~~~~~~~~~~~~~~~~~~~~~~
Change it to the normal prototype as it should have been from the
start.Thanks for catching this. I will add it to my tree. Eric
