Subject: [PATCH] tty: atmel_serial: Use of_property_present() for non-boolean properties
Date: Thu, 9 Jan 2025 12:20:52 -0600 [thread overview]
Message-ID: <20250109182053.3970547-1-robh@kernel.org> (raw)
The use of of_property_read_bool() for non-boolean properties is
deprecated in favor of of_property_present() when testing for property
presence.
As of_property_present() returns a boolean, use that directly
and simplify the code a bit while we're here.
