V4L/DVB (7552): videbuf-vmalloc: Corrects mmap code
There were some bugs on videobuf-vmalloc.
Basically, remap were called with a wrong parameter. Due to that, a later remap
were needed, generating the need of some hacks on videobuf-vmalloc and
videobuf-core.
This patch fixes the remap and removes the hacks.
TODO:
- V4L2_MEMORY_USERPTR is not implemented yet. This method should be
properly implemented, in order to work with a few userspace applications.
- The driver also doesn't implement V4L2_MEMORY_OVERLAY. This method is used
only by a few applications, and are becaming obsolete, due to the increment
of cpu performance. So, most apps prefer to retrieve data to an internal
buffer, doing some processing like de-interlacing.
