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.
