Occasional fail to initiate resume by incoming call, easy workaround proposed

Somebody in the thread at some point said:

| Calypso will not generate any interrupt until it sees CTS_MODEM fall
| for the first time after powering on. That leads to inability to
| trigger a first resume by calling or sending an SMS after turning on
| GSM and suspending.
|
| Userspace workaround:
|
| After the Calypso is powered on, do "echo 1 >
| /sys/bus/platform/devices/neo1973-pm-gsm.0/flowcontrolled; echo 0 >
| /sys/bus/platform/devices/neo1973-pm-gsm.0/flowcontrolled"

Shouldn't this be dealt with as part of the neo1973-pm-gsm ON action?

That driver is making a claim to twiddle bits needed to bring up the GSM
side, it looks like it should be folded into that, since it's a one-off
action at powerup?

Then it's independent of the rootfs.
