Subject: [PATCH] Documentation: migration-2025.06.0: mention char becoming unsigned
Date: Mon, 26 May 2025 21:27:23 +0200 [thread overview]
Message-ID: <20250526192723.1245057-1-a.fatoum@pengutronix.de> (raw)
unsigned chars are the default on ARM, so breakage is probably limited,
but let's point it out to be sure anyways.
