Subject[PATCH 1/3] device: property: add helpers to count items in string arrays
Date
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Instead of doing the following:

count = device_property_read_string_array(dev, propname, NULL, 0);

Let's provide inline helpers with hardcoded arguments for counting
strings in property arrays.
