Thanks for suggesting this Dmitry. I have now done that (and modified
cypress_ps2.c to set psmouse->state to the common PSMOUSE_CMD_MODE
instead). This makes the psmouse-base linkage entirely clean, I
think...
And it *almost* works! (Multitouch no longer works after suspend now).
Please see the forthcoming [PATCH v2] set, and thanks again for your
help.
