Subject: device: property: add helpers to count items in string arrays
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6b6ff4acb310a0351005474673f1e09a90020efd;p=linux.git

device: property: add helpers to count items in string arrays

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.
