Add a second working PNP_ID for a T470s

Add a second working PNP_ID for a T470s

The Lenovo Thinkpad T470s I own has a different touchpad with "LEN007a" instead of the already included PNP ID "LEN006c". However, my touchpad seems to work well without any problems using RMI. So this patch adds the other PNP ID.

So there are no visible issues when running the touchpad in PS/2 mode
compared to RMI4? (Just trying to figure out if it needs to go into
stable releases).

Do you know what trackpoint does the device have? 

Thanks.

Re: Re: Add a second working PNP_ID for a T470s

Hi Dmitry,

thanks for your reply. In the following I just add the content of my first email to this list:
#####
In dmesg I found the following:
psmouse serio1: synaptics: Your touchpad (PNP: LEN007a PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org.

After setting psmouse.synaptics_intertouch=1, touchpad and trackpoint still work fine. Also no problems with suspending my laptop.

The only problem is the following error meesage on shutdown:
rmi4_physical rmi4-00: Failed to read irqs, code=-6

/proc/bus/input/devices:
I: Bus=001d Vendor=06cb Product=0000 Version=0000
N: Name="Synaptics TM3145-006"

U: Uniq=
H: Handlers=event19 mouse1
B: PROP=21
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

Is there anything I can do, that the error messsage doesn't appear anymore? Should I not use RMI?
#####

As far as I can see, there is no issue running the touchpad with RMI4. The only difference to running it in PS/2 mode is the mentioned error message during shutdown. Is that error message only cosmetic, or a real issue? Can something be done to omit this error message?
Regarding the touchpad, is the above pasted information sufficient, or do you need anything else?

Thanks and best
Dennis

Re: Re: Re: Add a second working PNP_ID for a T470s

Hi Dmitry,

as far as I can see, there was no reply from you. If so, then I may have missed that, sorry for that.
As I said I am not aware of any issues when running the touchpad and trackpoint with RMI4. The only difference is the mentioned error message during shutdown, which I would like to get rid of, if possible.
Can the patch be merged? Anything missing for that?

Thanks and best
Dennis

Sorry, my fault as I have been busy lately and my patch queue grew
really long. The patch is applied, thank you for your work (and
patience).
