Subject: [PATCH] ARM: perf: Fix section mismatch on armpmu_init()

WARNING: vmlinux.o(.text+0xfb80): Section mismatch in reference
from the function armpmu_register() to the function
.init.text:armpmu_init()
The function armpmu_register() references
the function __init armpmu_init().
This is often because armpmu_register lacks a __init
annotation or the annotation of armpmu_init is wrong.

Just drop the __init marking on armpmu_init() because
armpmu_register() no longer has an __init marking.

Signed-off-by: Stephen Boyd <sboyd@...eaurora.org>

I doubt anyone is actually experiencing any problems because this
driver probes before kernel init is over. But the warning is a bit
annoying.
