Silence kernel log spam
For example each time you tap the on-screen keyboard the following is printed:
Jan 26 12:48:39 ubuntu-phablet kernel: aw8695_haptic_ram_config duration =10
Jan 26 12:48:39 ubuntu-phablet kernel: aw8695_haptic_ram_config wave index =1
During charging stuff like this keeps getting logged periodically:
Jan 26 12:49:23 ubuntu-phablet kernel: QCOM-STEPCHG: handle_jeita: handle_jeita ,temp:246, fcc_ua:4296000
Jan 26 12:49:23 ubuntu-phablet kernel: QCOM-STEPCHG: handle_jeita: handle_jeita ,FCC vote chg_disable_votable:false
Jan 26 12:49:23 ubuntu-phablet kernel: QCOM-STEPCHG: handle_vbatt_limit: f=500000, v=4383419
And when Wi-Fi is connected this keeps getting logged, is it a real problem?
Jan 26 12:49:52 ubuntu-phablet kernel: [Networ][0x15de0af094][10:49:52.582226] wlan: [1595:E:HDD] hdd_is_rcpi_applicable: 5406: mac addr is different from bssid connected
And these are just examples noticed on idle, there's probably way worse ones during e.g. phone calls, when a clock alarm goes off etc.
