   1 From: Eneas U de Queiroz <cotequeiroz@gmail.com>
   2 Subject: [PATCH] crypto: qce - add CRYPTO_ALG_KERN_DRIVER_ONLY flag
   3
   4 Set the CRYPTO_ALG_KERN_DRIVER_ONLY flag to all algorithms exposed by
   5 the qce driver, since they are all hardware accelerated, accessible
   6 through a kernel driver only, and not available directly to userspace.
