Subject: [RESEND PATCH] crypto: x509 - Replace kmalloc() + NUL-termination with kzalloc()
Date: Mon, 7 Apr 2025 10:22:47 +0200 [thread overview]
Message-ID: <20250407082247.741684-1-thorsten.blum@linux.dev> (raw)
Use kzalloc() to zero out the one-element array instead of using
kmalloc() followed by a manual NUL-termination.
No functional changes intended.
