From: Sarannya S <sarannya@xxxxxxxxxxxxxxxx> 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'.
