Subject: [PATCH 1/1] aiodio: Fix format string for 32bit
Date:   Wed,  3 Aug 2022 19:32:11 +0200
Message-Id: <20220803173211.14292-1-pvorel@suse.cz>

On 32bit char pointer is int and size_t is unsigned int,
Cast to long / unsigned long.

Hi,

IMHO %zu is C99, we don't define -std and my gcc 12 uses by default -std=gnu17.
Therefore I'm surprised that %zu does not work.

Based on Andrea patch:
https://patchwork.ozlabs.org/project/ltp/patch/20220803120905.3107-1-andrea.cervesato@suse.com/

Kind regards,
Petr
