Subject: [PATCH v2 0/4] Add ff-memless-next and make hid-lg4ff use it

Hi everybody,

this patch series is a result of my work to improve FFB support for memoryless
devices. ff-memless-next is an improvement over the currently available
ff-memless which is well suited for joypads but cannot handle more advanced
devices such as racing wheels properly. As I have explained in one of RFCs
regarding ff-memless-next, the extent of the changes makes implementing
ff-memless-next as a patch to ff-memless unfeasible. As of now there is a total
of 27 drivers using ff-memless (including lg4ff) - a lot of them joypads.
I do not have access to any FFB joypad at the moment so I cannot
implement the functionality required to handle joypads properly - namely FF_RUMBLE
and emulation of FF_PERIODIC through FF_RUMBLE.
The plan is to implement the missing functionality and replace ff-memless completely
in the future. 

Second part of this series ports lg4ff driver over to ff-memless-next.
The immediate benefit of this is support of all periodic effects and ramp effect.

v2 addresses a few issues that have not been noticed at the time v1 was
submitted. Specific fixes are mentioned in the respective patches.
