However, there was a very strong opposition from DT maintainers
to adding any bit related configuration to DT.
The current solution was designed to be a trade-off between

The DMA transfer must be aligned to a specific value. If userptr is not aligned
to DMA requirements then unexpected corruptions of the memory may occur before
or after a buffer. To prevent such situations, all unligned userptr buffers
are rejected
Most operations on DMA and DMABUF framework need page
aligned buffers. This fix guarantees this requirement
for vb2-dma-contig buffers.

This patch removes a reference to alloc_ctx from an instance of a DMA
contiguous buffer. It helps to avoid a risk of a dangling pointer if the
context is released while the buffer is still valid. Moreover it removes one
dereference step while accessing a device structure.
