[PATCH 4.9 51/86] ARM: omap2: hide omap3_save_secure_ram on non-OMAP3 builds

From: Greg Kroah-Hartman
Date: Fri Mar 16 2018 - 12:57:11 EST


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

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

From: Arnd Bergmann <arnd@xxxxxxxx>

commit 863204cfdae98626a92535ac928ad79f4d6b74ff upstream.

In configurations without CONFIG_OMAP3 but with secure RAM support,
we now run into a link failure:

arch/arm/mach-omap2/omap-secure.o: In function `omap3_save_secure_ram':
omap-secure.c:(.text+0x130): undefined reference to `save_secure_ram_context'

The omap3_save_secure_ram() function is only called from the OMAP34xx
power management code, so we can simply hide that function in the
appropriate #ifdef.

Fixes: d09220a887f7 ("ARM: OMAP2+: Fix SRAM virt to phys translation for save_secure_ram_context")
