Subject: [PATCH 5/9] treewide: specify __printf attribute directly on static definition
Date: Tue, 27 May 2025 22:13:55 +0200	[thread overview]
Message-ID: <20250527201359.889550-5-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20250527201359.889550-1-a.fatoum@pengutronix.de>

On a declaration, __printf can come at the end, but for a definition, it
is not accepted after argument list and before the curly brace, so
instead of having a declaration with the attribute as well as a
definition, just have a single definition and move the __printf to the
start.
