Linux 5.17.y drivers/power/reset/odroid-reboot.c

There appears to be a fail in the following function concerning the ODROID-COMMON: power:reset: Add odroid support commit.

 CC      drivers/power/reset/odroid-reboot.o
drivers/power/reset/odroid-reboot.c: In function ‘odroid_restart_probe’:

When deselected from the defconfig the build completes fine, of course the boards no longer have the ability to reboot correctly. Just thought you would like to know. Thank you!

Thanks, temporary fix is uploaded. Let me look into this error again later. :)
