ARM: OMAP: fix fault in enter_full_retention()
In omap24xx_cpu_suspend assembly routine, the r2 register which holds the address of the SDRC_POWER reg is set to zero before the value is written back triggering a fault due to writing to address zero. It's hard to tell where this change was introduced since this file has been moved and merged. While this fix prevents a crash, suspend on my n810 is broken with current kernels. I never come out of suspend. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
