Various drivers count and iterate over OF children nodes via
of_get_child_count and for_each_child_of_node. Instead they should use
of_get_available_child_count and for_each_available_child_of_node, so
that if a given node has the `status` property set to `disabled`, the
child will be ignored.Signed-off-by: Marek Behún

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".The Coccinelle script used for this was:

of_find_node_by_name() calls of_node_put() on its "from" parameter.
To counter this, mc13xxx_led_probe_dt() calls of_node_get() first.Use of_get_child_by_name() instead to get rid of the refcount hack.

With the addition of a platform device mfd_cell pointer, MFD drivers

This allows for an mfd_cell->mfd_data removal and thus keep the

The cell's platform_data is now accessed with a helper function;
change clients to use that, and remove the now-unused data_size.Note that mfd-core no longer makes a copy of platform_data, but the
mc13xxx-core driver creates the pdata structures on the stack. In
order to get around that, the various ARM mach types that set the
pdata have been changed to hold the variable in static (global) memory.
Also note that __initdata references in aforementioned pdata structs
have been dropped.Signed-off-by: Andres Salomon
