Subject: powerpc: Correctly disable latent entropy GCC plugin on prom_init.o
From: Andrew Donnellan <andrew.donnellan@xxxxxxxxxxx>
commit eac6f8b0c7adb003776dbad9d037ee2fc64f9d62 upstream.
Commit 38addce8b600 ("gcc-plugins: Add latent_entropy plugin") excludes
certain powerpc early boot code from the latent entropy plugin by adding
appropriate CFLAGS. It looks like this was supposed to cover
prom_init.o, but ended up saying init.o (which doesn't exist) instead.
Fix the typo.
Fixes: 38addce8b600 ("gcc-plugins: Add latent_entropy plugin")
