[PATCH v2 1/3] device: property: add helpers to count items in string arrays
From: Bartosz Golaszewski
Date: Wed Sep 09 2020 - 04:55:28 EST
From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>
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.
