As the subject says i2cdesingware is flooding my logfiles with every movement of the mousepointer with my trackpad on a Dell XPS 15 9500 with messege blocks like this:
| Code: |
# dmesg
[...]
[ 8497.395208] i2c_designware i2c_designware.1: i2c_dw_xfer: msgs: 1
[ 8497.395262] i2c_designware i2c_designware.1: enabled=0x1 stat=0x10
[ 8497.395407] i2c_designware i2c_designware.1: enabled=0x1 stat=0x514
[ 8497.395475] i2c_designware i2c_designware.1: enabled=0x1 stat=0x514

Debug mode seems to be enabled. Please check your kernel and/or module parameters.
| Code: | | /usr/src/linux/drivers/i2c/busses/i2c-designware-master.c:767: dev_dbg(dev->dev, "enabled=%#x stat=%#x\n", enabled, stat); |
