kernel 5.10.11 overwrote my private UEFI key

[stan]

Hi,

I compile a custom kernel from the Fedora src.rpm.  When I compiled the
5.10.11 kernel, it overwrote my private key when I installed it.  The
last 5.10 kernel I compiled and installed, 5.10.4, did not.  I don't
expect any kind of fix since it is a custom compile, just putting this
out there as a data point in case anyone else runs into this and is
scratching their head.
