[PATCH 4.9 028/175] powerpc/module64: Fix comment in R_PPC64_ENTRY handling

[Greg Kroah-Hartman]

From: Michael Ellerman <mpe@xxxxxxxxxxxxxx>

commit 2fb0a2c989837c976b68233496bbaefb47cd3d6f upstream.

The comment here is wrong, the addi reads from r2 not r12. The code is
correct, 0x38420000 = addi r2,r2,0.

Fixes: a61674bdfc7c ("powerpc/module: Handle R_PPC64_ENTRY relocations")
