Subject: [PATCH] Handle crypto modules with and without modaliases
|
|
|
712866 |
|
|
|
712866 |
If new kernels have modules split out, handle the case, where modules
|
|
|
712866 |
have to modalias and just install them.
|
|
|
712866 |
|
|
|
712866 |
Also add the crypto drivers and names to host_modalias.
