Regressions on mips the rt305x_defconfig builds failed with gcc-12
the stable-rc v6.6.83-167-gd16a828e7b09

First seen on the v6.6.83-167-gd16a828e7b09
 Good: v6.6.83
 Bad: v6.6.83-167-gd16a828e7b09

* mips, build
  - gcc-12-rt305x_defconfig

Regression Analysis:
 - New regression? Yes
 - Reproducibility? Yes
