+# Fix Dell XPS haptic touchpad losing haptic feedback after suspend/resume.
+# The I2C controller's runtime power management aggressively suspends the touchpad,
+# and on resume the haptic engine sometimes fails to reinitialize.
+# This udev rule keeps the I2C controller always on to prevent that.
+# Applies to any Dell XPS with the Synaptics haptic touchpad (06CB:D01A).
