Subject: [char-misc-next v2 0/7] mei: Add DMA ring

This is a resend of the second part for the mei dma ring,
that was left out.

This series adds an alternative method for
transferring data between the mei driver and the device
via a DMA ring. The DMA ring allows transferring
data in bigger chunks, up to 128K, than the HW ring 512B.
The actual sizes depend on particular MEI generations.
The HW ring is faster for packets that fits
into the HW ring while a packet that would require
fragmentation is faster to send via the DMA ring.

V2: 1. Use single license for the new dma-ring.c file.
    2. Adjust kdoc to new requirements:
