Pull i2c updates from Wolfram Sang:
 "New stuff from the I2C world:

   - in the core, getting irqs from ACPI is now similar to OF

   - new driver for MediaTek MT7621/7628/7688 SoCs

   - bcm2835, i801, and tegra drivers got some more attention

   - GPIO API cleanups

   - cleanups in the core headers

   - lots of usual driver updates"

Merge tag 'at24-v5.3-updates-for-wolfram' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into i2c/for-5.3

2019-06-29T11:01:34+00:00

at24: updates for v5.3

- simplify the probing code by using devm_i2c_new_dummy_device()
- simplify the code further by moving the code around a bit
- use struct_size() instead of calculating the required structure size
  by hand
- remove any references to now removed platform data from comments

eeprom: at24: modify a comment referring to platform data

2019-06-27T13:55:08+00:00

We no longer have platform data in at24, so this comment is invalid.
Make it refer to device tree & properties instead.

eeprom: idt_89hpesx: remove unneeded csr_file variable

2019-06-19T17:39:28+00:00

The csr_file variable was only ever set, never read.  So remove it from
struct idt_89hpesx_dev as it is pointless to keep around.

eeprom: at24: use struct_size() in devm_kzalloc()

2019-05-31T07:06:52+00:00

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 = devm_kzalloc(dev, size, GFP_KERNEL);

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

instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);

Notice that, in this case, variable at24_size is not necessary, hence it
is removed.

This code was detected with the help of Coccinelle.
