Subject: [PATCH V9 0/3] rpmsg signaling/flowcontrol patches

From: Sarannya S <sarannya@....qualcomm.com>

Changes from V8:
* Updated the argument for RPMSG_SET_INCOMING_FLOWCONTROL to int.
* Return -EINVAL if arg > 1 in RPMSG_SET_INCOMING_FLOWCONTROL.

Key changes from earlier revisions:
* Added two new RPMSG IOCTLs for rpmsg_char- RPMSG_GET_SIGNAL_IOCTRL and RPMSG_SET_SIGNAL_IOCTRL, to set/get the flow.
* Updated the cmd name 'RPM_CMD_SIGNALS' to 'GLINK_CMD_SIGNALS'.
* Return EOPNOTSUPP error in rpmsg_set_flow_control(), if the backend does not support flow control ops.
* For rpmsg_set_flow_control, change "EXPORT_SYMBOL" to "EXPORT_SYMBOL_GPL".
* Change return type of qcom_glink_handle_signals() from int to void.
* Added destination address of the endpoint as parameter in rpmsg_set_flow_control.
* Changed 'remote_flow' to bool type, and updated it's evaluation.
* Updated evaluation of 'set' in rpmsg_char as 'set = !!arg'.
