#12426: Hang during runin suspend

Comment(by pgf):

 to be clear, the code in mmp3_pm_enter_d2() looks like:
 pr_err("%s 9\n", __func__);

         __asm__ __volatile__ ("wfi");
 pr_err("%s 10\n", __func__);

         printk("after resume\n");


 which is to say, not seeing step 10 is consistent with failing to resume.
 or, perhaps, failing to suspend, depending on whether SOC_SLEEP has risen
 (i.e., the power LED has gone out) in the meantime.
