Subject: [PATCH 1/3] include: debug_ll: define puthexc_ll
Date: Wed, 19 Oct 2022 14:38:15 +0200 [thread overview]
Message-ID: <20221019123817.1659468-1-a.fatoum@pengutronix.de> (raw)
puthex_ll prints a single zero-padded unsigned long, which for a single
byte is not very readable, especially on 64-bit systems. Define
puthexc_ll() as well, which just accepts a byte and formats its nibbles
as hexadecimal characters.
