The last field of the driver_data->leds[] array is used to store the
special toggle for setting all leds simultaneously, so we need to allocate
appropriate number of led_classdev pointers.

We usually group drivers on a per-vendor basis, implementing device-specific
deviations from the standard in vendor-specific driver.

This patch to the SRW-S1 driver adds the ability to control all
LEDs simultaneously as testing showed that it was slow (noticably!!)
when seting or clearing all the LEDs in turn.

It adds a 'RPMALL' LED, whose behavoir is asserted to all the LEDs in
the bar graph, individual LEDs can subsequently be turned on/off
individually.

This patch to the SRW-S1 driver adds support for the LED RPM
meter on the front of the device. The LEDs are controlled via
/sys/class/leds interface, with an individual control for each
of the 15 LEDs.

This patch to the SRW-S1 driver re-writes the HID descriptor
to insert a section for the 3 dials on the device, previously
these were contained within a 'Manufacturer Specific' usage
page.

Add support the SRW-S1 by patching HID descriptor to read axis
as Generic Desktop X, Y and Z (rather than Usage page being
'Simulation').
