Subject: [PATCH 1/5] commands: rksecure: exit if invalid integer passed to -b
Date: Tue, 22 Sep 2026 12:47:52 +0200	[thread overview]
Message-ID: <20260922104813.317584-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20260922104813.317584-1-a.fatoum@pengutronix.de>

kstrtouint() is defined with __must_check and we will enforce this in a
follow-up commit. The rksecure command used the function, but didn't check
its return value. Fix this.
