Input: elantech - fix protocol errors for some trackpoints in SMBus mode

2021-03-07T11:34:03+00:00

commit e4c9062717feda88900b566463228d1c4910af6d upstream. There are some version of Elan trackpads that send incorrect data when in SMbus mode, unless they are switched to use 0x5f reports instead of standard 0x5e. This patch implements querying device to retrieve chips identifying data, and switching it, when needed to the alternative report.

f30_data in rmi_device_platform_data could be also referenced by RMI function 3A, so rename it and the structure name to avoid confusion.
