   8 commit eac6f8b0c7adb003776dbad9d037ee2fc64f9d62 upstream.

  10 Commit 38addce8b600 ("gcc-plugins: Add latent_entropy plugin") excludes
  11 certain powerpc early boot code from the latent entropy plugin by adding
  12 appropriate CFLAGS. It looks like this was supposed to cover
  13 prom_init.o, but ended up saying init.o (which doesn't exist) instead.
  14 Fix the typo.
