Description:
|
|
This read/write attribute allows users to set read-write
|
|
devices as read-only and back to read-write from userspace.
|
|
This can be used to unlock and relock write-protection of
|
|
devices which are generally locked, except during sporadic
|
|
programming operation.
|
|
Read returns '0' or '1' for read-write or read-only modes
|
|
respectively.
|
|
Write parses one of 'YyTt1NnFf0', or [oO][NnFf] for "on"
|
|
and "off", i.e. what kstrtobool() supports.
