Subject: [PATCH v4 5/7] fbdev: au1100fb: Replace custom printk wrappers by pr_*
Date: Sun, 15 Feb 2026 14:58:32 +0100 [thread overview]
Message-ID: <6c72b8bcd1b608d1ec7227b8d1aa6c7a73148a05.1771163316.git.u.kleine-koenig@baylibre.com> (raw)
In-Reply-To: <cover.1771163316.git.u.kleine-koenig@baylibre.com>
The global wrappers also have the advantage to do stricter format
checking, so the pr_devel formats are also checked if DEBUG is not
defined. The global variants only check for DEBUG being defined and not
its actual value, so the #define to zero is dropped, too.
There is only a slight semantic change as the (by default disabled)
debug output doesn't contain __FILE__ any more.
Signed-off-by: Uwe Kleine-König <u.kleine-koenig@baylibre.com>
