[ Upstream commit a3a22373fce576560757f5616eb48dbf85891d9c ]
If the rootfs have a legacy A200 firmware, currently the driver will complain each time the hw is reinited (which can happen a lot). E.g. with GL testsuite the hw is reinited after each test, spamming the console.
Make sure that the message is printed only once: when we detect the firmware that doesn't support protection.
