[ Upstream commit 61005d65b6c7dcf61c19516e6ebe5acc02d2cdda ] My Logitech M185 (PID:4038) 2.4 GHz wireless HID++ mouse is causing intermittent errors like these in the log: [11091.034857] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09 [12388.031260] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09 [16613.718543] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09 [23529.938728] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09 We are already silencing error-code 0x09 (HIDPP_ERROR_RESOURCE_ERROR) errors in other places, lets do the same in hidpp20_batterylevel_get_battery_capacity to remove these harmless, but scary looking errors from the dmesg output.
