-/** A note about RMI4 F11 register structure.
- *
- * There may be one or more individual 2D touch surfaces associated with an
- * instance for F11. For example, a handheld device might have a touchscreen
- * display on the front, and a touchpad on the back. F11 represents these touch
- * surfaces as individual sensors, up to 7 on a given RMI4 device.
- *
- * The properties for
- * a given sensor are described by its query registers. The number of query
- * registers and the layout of their contents are described by the F11 device
- * queries as well as the per-sensor query information. The query registers
- * for sensor[n+1] immediately follow those for sensor[n], so the start address
- * of the sensor[n+1] queries can only be computed if you know the size of the
- * sensor[n] queries. Because each of the sensors may have different
- * properties, the size of the query registers for each sensor must be
- * calculated on a sensor by sensor basis.
- *
- * Similarly, each sensor has control registers that govern its behavior. The
- * size and layout of the control registers for a given sensor can be determined
- * by parsing that sensors query registers. The control registers for
- * sensor[n+1] immediately follow those for sensor[n], so you can only know
- * the start address for the sensor[n+1] controls if you know the size (and
- * location) of the sensor[n] controls.
- *
- * And in a likewise fashion, each sensor has data registers where it reports
- * its touch data and other interesting stuff. The size and layout of a
- * sensors data registers must be determined by parsing its query registers.
- * The data registers for sensor[n+1] immediately follow those for sensor[n],
- * so you can only know the start address for the sensor[n+1] controls if you
- * know the size (and location) of the sensor[n] controls.
- *
- * The short story is that we need to read and parse a lot of query
- * registers in order to determine the attributes of a sensor[0]. Then
- * we need to use that data to compute the size of the control and data
- * registers for sensor[0]. Once we have that figured out, we can then do
- * the same thing for each subsequent sensor.
- *
- * The end result is that we have a number of structs that aren't used to
- * directly generate the input events, but their size, location and contents
- * are critical to determining where the data we are interested in lives.
- *
- * At this time, the driver does not yet comprehend all possible F11
- * configuration options, but it should be sufficient to cover 99% of RMI4 F11
- * devices currently in the field.

+/** A note about RMI4 F11 register structure.
+ *
+ * There may be one or more individual 2D touch surfaces associated with an
+ * instance for F11. For example, a handheld device might have a touchscreen
+ * display on the front, and a touchpad on the back. F11 represents these touch
+ * surfaces as individual sensors, up to 7 on a given RMI4 device.
+ *
+ * The properties for
+ * a given sensor are described by its query registers. The number of query
+ * registers and the layout of their contents are described by the F11 device
+ * queries as well as the per-sensor query information. The query registers
+ * for sensor[n+1] immediately follow those for sensor[n], so the start address
+ * of the sensor[n+1] queries can only be computed if you know the size of the
+ * sensor[n] queries. Because each of the sensors may have different
+ * properties, the size of the query registers for each sensor must be
+ * calculated on a sensor by sensor basis.
+ *
+ * Similarly, each sensor has control registers that govern its behavior. The
+ * size and layout of the control registers for a given sensor can be determined
+ * by parsing that sensors query registers. The control registers for
+ * sensor[n+1] immediately follow those for sensor[n], so you can only know
+ * the start address for the sensor[n+1] controls if you know the size (and
+ * location) of the sensor[n] controls.
+ *
+ * And in a likewise fashion, each sensor has data registers where it reports
+ * its touch data and other interesting stuff. The size and layout of a
+ * sensors data registers must be determined by parsing its query registers.
+ * The data registers for sensor[n+1] immediately follow those for sensor[n],
+ * so you can only know the start address for the sensor[n+1] controls if you
+ * know the size (and location) of the sensor[n] controls.
+ *
+ * The short story is that we need to read and parse a lot of query
+ * registers in order to determine the attributes of a sensor[0]. Then
+ * we need to use that data to compute the size of the control and data
+ * registers for sensor[0]. Once we have that figured out, we can then do
+ * the same thing for each subsequent sensor.
+ *
+ * The end result is that we have a number of structs that aren't used to
+ * directly generate the input events, but their size, location and contents
+ * are critical to determining where the data we are interested in lives.
+ *
+ * At this time, the driver does not yet comprehend all possible F11
+ * configuration options, but it should be sufficient to cover 99% of RMI4 F11
+ * devices currently in the field.
