Subject: [PATCH 3.18 32/39] staging: emxx_udc: remove incorrect __init annotations

3.18-stable review patch.  If anyone has any objections, please let me know.

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

From: Arnd Bergmann <arnd@...db.de>

commit 4f3445067d5f78fb8d1970b02610f85c2f377ea4 upstream.

The probe function is not marked __init, but some other functions
are. This leads to a warning on older compilers (e.g. gcc-4.3),
and can cause executing freed memory when built with those
compilers:

WARNING: drivers/staging/emxx_udc/emxx_udc.o(.text+0x2d78): Section mismatch in reference from the function nbu2ss_drv_probe() to the function .init.text:nbu2ss_drv_contest_init()

This removes the annotations.

Fixes: 33aa8d45a4fe ("staging: emxx_udc: Add Emma Mobile USB Gadget driver")
