Subject: powerpc/module64: Fix comment in R_PPC64_ENTRY handling
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2fb0a2c989837c976b68233496bbaefb47cd3d6f;p=linux.git

powerpc/module64: Fix comment in R_PPC64_ENTRY handling

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")
