[PATCH 1/1] ARM: prov-v7: cpu_do_suspend corrupt r11

[PATCH 1/1] ARM: prov-v7: cpu_do_suspend corrupt r11

[Chen Gang]

ARM V7 version of cpu_do_suspend() [cpu_v7_do_suspend] is called
with C calling conventions from arch/arm/kernel/suspend.c - but
cpu_v7_do_suspend() use R11. The temporary register R12 is unused,
so change reference from R11 to R12.
