+From: Eneas U de Queiroz <cotequeiroz@gmail.com>
+Subject: [PATCH] crypto: qce - add CRYPTO_ALG_KERN_DRIVER_ONLY flag
+
+Set the CRYPTO_ALG_KERN_DRIVER_ONLY flag to all algorithms exposed by
+the qce driver, since they are all hardware accelerated, accessible
+through a kernel driver only, and not available directly to userspace.
+
