[ Upstream commit abdbf8764f ]
Some devices only support SINE periodic effect although they advertise
support for all PERIODIC effect in their HID descriptor. Some just do
nothing when trying to play such an effect (upload goes fine), some express
undefined behavior like turning to one side.
This quirk forces all the periodic effects to be uploaded as SINE. This is
acceptable as all these effects are similar in nature and are mostly used as
rumble. SINE is the most popular with others seldom used (especially SAW_UP
and SAW_DOWN).
Fixes periodic effects for PXN and LITE STAR wheels
