Subject: [PATCH 1/4] dmidecode: use common function to get SMBIOS version
|
|
|
3ea658 |
|
|
|
3ea658 |
Move SMBIOS version code in separate function as it's more readable
|
|
|
3ea658 |
and can be used by others when it's required.
|
|
|
3ea658 |
In paticular, it can be used when dmi sysfs support is added.
