Subject: backlight: hx8357: Use of_property_present() for testing DT property presence
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=796bf946c42644b047c5ad5575906ff9c397fbda;p=linux.git

backlight: hx8357: Use of_property_present() for testing DT property presence

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.
