Hi All,
This series was written in parallel with reading and understanding the
vchiq code. So excuse me for the lack of logic in the sequence of
patches.
The main focus was to delete as much code as possible, I've counted
around 550 lines, which is not bad. Apart from that there are some
patches
The resulting code is way more readeable and intuitive compared to plain
list_for_each.

The function is passed to vchiq_core.c for it to go trough all the

the element is empty, in which case look for

VCHIQ bulk transfers are what most people call DMA transfers. The CPU
sends a list of physical addresses to the VideoCore which then access
the memory directly without the need for CPU interaction. With this

The concept of VCHI_MEM_HANDLE_T is introduced by this header file and
was meant to be used with bulk transfers. After a quick look in
vchiq_core.c it is pretty clear that it actually accomplishes nothing
nor alters the bulk transfers in any way.

vchiq_init_state() checks the initial contents of slot_zero are correct.
These are set in vchiq_init_slots(), using the same hard-coded defaults
as the checks. Both functions are called sequentially and Video Core
isn't yet aware of the slot's address. There is no way the contents of
slot_zero chan
All the memory operations featured in this file modify/access memory
that is only accessed by the CPU. So we can assume that all the memory
barrier handling done by the completion routines is good enough for us.

It is preferred in the kernel to avoid using semaphores to wait for
events, as they are optimised for the opposite situation; where the
common case is that they are available and may block only occasionally.

Moves the allocation of a chardev region and class creation to the init
function of the driver since those functions are meant to be run on a
per driver basis, as opposed to the code run in the probe function which
is run in a per device basis.

Both functions checked the minor number of the cdev prior running the
code. This was useless since the number of devices is already limited by
alloc_chrdev_region.
This removes the check and reindents the code where relevant.
