Subject: [PATCH] powerpc: fsl_rio: Use snprintf() in fsl_rio_setup()
Date: Tue, 30 Jun 2026 16:49:50 +0200 [thread overview]
Message-ID: <20260630144951.692473-2-thorsten.blum@linux.dev> (raw)
While the current code works correctly, replace the unbounded sprintf()
with the safer snprintf() in fsl_rio_setup() to follow secure coding
best practices.
