Subject: [PATCH] Input: Use of_property_read_bool() for boolean properties
Date: Fri, 10 Mar 2023 08:47:08 -0600 [thread overview]
Message-ID: <20230310144708.1542751-1-robh@kernel.org> (raw)
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.
Convert reading boolean properties to to of_property_read_bool().
