[STABLE v6.6 1/5] HID: hid-steam: Make client_opened a counter

[Lee Jones]

From: Vicki Pfau <vi@xxxxxxxxxxx>

[ Upstream commit 555b818adb97eca70210a49ba3f1d27882dde092 ]

The client_opened variable was used to track if the hidraw was opened by any
clients to silence keyboard/mouse events while opened. However, there was no
counting of how many clients were opened, so opening two at the same time and
then closing one would fool the driver into thinking it had no remaining opened
clients.
