[ Upstream commit 0b7c9528facdb5a73ad78fea86d2e95a6c48dbc4 ]
This patch fixes an issue where the touchpad cursor movement becomes slow on the Dell Precision 5560. Force the touchpad freq to 100khz as a workaround.
Tested on Dell Precision 5560 with 6.14 to 6.14.6. Cursor movement is now smooth and responsive.
