Subject: [PATCH 2/2] EP11: Fix host library version query
|
|
|
71f833 |
|
|
|
71f833 |
Look at release and modification level, not just the modification level.
|
|
|
71f833 |
Release and modification level are encoded into the one byte minor
|
|
|
71f833 |
field of a CK_VERSION. The high order 4 bits are the release number, the
|
|
|
71f833 |
low order 4 bits the modification level.
|
|
|
71f833 |
|
|
|
71f833 |
This allows host library version checks for release and modification levels.
