[ Upstream commit 411a20db905b44e18cc9129b745f1d5deba4eae5 ]
Since commit 680ee411a98e ("HID: logitech-hidpp: Fix connect event race")
the following messages appear in the kernel log from time to time:
logitech-hidpp-device 0003:046D:408A.0005: HID++ 4.5 device connected.
logitech-hidpp-device 0003:046D:408A.0005: HID++ 4.5 device connected.
logitech-hidpp-device 0003:046D:4051.0006: Disconnected
logitech-hidpp-device 0003:046D:408A.0005: Disconnected
As discussed, print the first per-device "device connected" message
at info level, demoting subsequent messages to debug level. Also,
demote the "Disconnected message" to debug level unconditionally.
