[PATCH v2] Input: elan_i2c - always output the device information

From: Benjamin Tissoires
Date: Thu Oct 13 2016 - 07:48:27 EST

it's always easier to retrieve these information in bug reports when
it is always printed in the dmesg.

changes in v2:
- split the version information message and the touchpad characteristics
- keep sending the versions as info (on one line)
- send the characteristics on debug only

Hi Dmitry,

This is a respin of one of the patches I sent for elan_i2c. Given that you
applied the fixed one for SMBus and that I don't currently have a way to
check from I2C if the trackstick is going to be used, this one is the only
one left (also given SMBus Host Notify might meld into client->irq).

So, well, yes, there it comes, a single patch which IMO is useful
when we receive bug reports.
