The main purpose of this function is to exclude ME devices without support for MEI/HECI interface from binding Currently affected systems are C600/X79 based servers that expose PCI device even though it doesn't supported ME Interface. MEI driver accessing such nonfunctional device can corrupt the system. Signed-off-by: NTomas Winkler <tomas.winkler@intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>

Before ME watchdog was exported through standard watchdog interface it was closed and started together with the mei device. The major issue is that closing ME watchdog disabled also MEI device, to fix this the watchdog state machine has to be independent from MEI state machine.

Change mei_write_message's return type from bool to int to enable propagation of the error code up to caller functions. The function now returns -EIO when low level write fails and 0 on success. A similar change is done in intermediate caller functions: mei_send_flow_control, mei_connect, and mei_disconnect This makes code more alike to typical Linux kernel error handling.

1. No need to check if a list is empty before list_for_each_ looping as this is already checked by loop stopping conditional. The side effect is reduced indentation depth from: if (!list_empty) list_for_each() to: list_for_each() 2. drop cb_ prefix from cl_pos, cl_next variables used in list_for_each loops.
