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. Michal M.
