media: atomisp: fix -Wdangling-pointer warning
ia_css_rmgr_acq_vbuf() uses a local on stack
"struct ia_css_rmgr_vbuf_handle v" variable.
When this path using this is hit, either the rmgr_pop_handle() call
will make *handle point to another vbuf-handle, or because
v.count == 0, ia_css_rmgr_refcount_retain_vbuf() will alloc a new
vbuf-handle and make *handle point to it.
So on leaving the function *handle will never point to the on stack
vbuf-handle, but gcc does not know this and emits the following:
drivers/staging/media/atomisp/pci/runtime/rmgr/src/rmgr_vbuf.c: In function ‘ia_css_rmgr_acq_vbuf’:

media: atomisp: revert "don't pass a pointer to a local variable"
The gcc is warning about returning a pointer to a local variable
is a false positive.
The type of handle is "struct ia_css_rmgr_vbuf_handle **" and
"h.vptr" is left to NULL, so the "if ((*handle)->vptr == 0x0)"
check always succeeds when the "*handle = &h;" statement which
gcc warns about executes. Leading to this statement being executed:
rmgr_pop_handle(pool, handle);
If that succeeds, then *handle has been set to point to one of
the pre-allocated array of handles, so it no longer points to h.
If that fails the following statement will be executed:
/* Note that handle will change to an internally maintained one */
ia_css_rmgr_refcount_retain_vbuf(handle);
Which allocated a new handle from the array of pre-allocated handles
and then makes *handle point to this. So the address of h is actually
never returned.
The fix for the false-postive compiler warning actually breaks the code,
the new:
**handle = h;
is part of a "if (pool->copy_on_write) { ... }" which means that the
handle where *handle points to should be treated read-only, IOW
**handle must never be set, instead *handle must be set to point to
a new handle (with a copy of the contents of the old handle).
The old code correctly did this and the new fixed code gets this wrong.
Note there is another patch in this series, which fixes the warning
in another way.

The three bugs are here:
__func__, s3a_buf->s3a_data->exp_id);
__func__, md_buf->metadata->exp_id);
__func__, dis_buf->dis_data->exp_id);
The list iterator 's3a_buf/md_buf/dis_buf' will point to a bogus
position containing HEAD if the list is empty or no element is found.
This case must be checked before any use of the iterator, otherwise
it will lead to a invalid memory access.
To fix this bug, add an check. Use a new variable '*_iter' as the
list iterator, while use the old variable '*_buf' as a dedicated
pointer to point to the found element.

media: staging: media: atomisp: Use kmap_local_page() in hmm_store()
The use of kmap() is being deprecated in favor of kmap_local_page()
where it is feasible. The same is true for kmap_atomic().
In file pci/hmm/hmm.c, function hmm_store() test if we are in atomic
context and, if so, it calls kmap_atomic(), if not, it calls kmap().
First of all, in_atomic() shouldn't be used in drivers. This macro
cannot always detect atomic context; in particular, it cannot know
about held spinlocks in non-preemptible kernels.
Notwithstanding what it is said above, this code doesn't need to care
whether or not it is executing in atomic context. It can simply use
kmap_local_page() / kunmap_local() that can instead do the mapping /
unmapping regardless of the context.
With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible. Therefore, hmm_store()() is a function where the use
of kmap_local_page() in place of both kmap() and kmap_atomic() is
correctly suited.
Convert the calls of kmap() / kunmap() and kmap_atomic() /
kunmap_atomic() to kmap_local_page() / kunmap_local() and drop the
unnecessary tests which test if the code is in atomic context.

media: atomisp: remove private acceleration ioctls
These ioctls allow userspace to load custom programs into the ISP, which:
a) Seems dangerous
b) Cannot be used by opensource userspace since there is no FOSS code to
create such programs
b) These seem to be unused even by the Android closed source camera code
(they don't show up in a strace of the camera app)
So removing these seems be a good idea. Another reason to remove these is
that atomisp_acc_map() is the only user of the userptr functionality in
hmm_alloc(), so it gets in the way of further cleanups / simplification
of the hmm code.
