    Subject[PATCH 4.9 012/103] powerpc: Correctly disable latent entropy GCC plugin on prom_init.o
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Andrew Donnellan <andrew.donnellan@au1.ibm.com>

    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.
