Yes, I believe previous commit is the wrong fix on the same problem.

This commit changes exactly the same place as the previous commit,
v9.0.0-274-gb11f981452, "hw/loongarch: Fix fdt memory node wrong 'reg'".

Was it the wrong fix?

Note the previous commit isn't in any released version of qemu.  So
when picking up for any stable release, both needs to be picked up :)

Thanks,
