regulator: wm8400: Get rid of wm8400_block_read/wm8400_set_bits functions
The only user of wm8400_block_read/wm8400_set_bits functions is the
wm8400 regulator driver. At the context of all the callers, we can
use regmap_bulk_read/regmap_update_bits directly.
Thus remove wm8400_block_read/wm8400_set_bits functions.

regulator: da9062: Use struct_size() in devm_kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL)

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = alloc(struct_size(instance, entry, count), GFP_KERNEL)

Notice that, in this case, variable size is not necessary, hence it is
removed.

This code was detected with the help of Coccinelle.
