This one has been "fixed" by commit d0afcfeb9e381 ("kbuild: Disable
-Wdefault-const-init-unsafe"). It is also part of v6.1.141-rt52 and

For RT, or kernels in general, it should be enough to test the last
kernel/ tag from each release branch. The older ones, such at as this
one, may contain bugs which will not be fixed in "this" release but a
subsequent release may contains a fix if possible.
