[PATCH] Input: synaptics-rmi4 - Only read the F54 query registers which are used

2017-06-20 Thread Andrew Duggan
The F54 driver is currently only using the first 6 bytes of F54 so there is no need to read all 27 bytes. Some Dell systems (Dell XP13 9333 and similar) have an issue with the touchpad or I2C bus when readiing reports larger then 16 bytes. Reads larger then 16 bytes are reported in two HID reports.
