[ros-dev] [ros-diffs] [hbelusca] 58235: [SMSS] Load the Win32k driver from the path mentioned in the Kmode value of the registry, not via a hardcoded value.

[Alex Ionescu]

This change is not correct. The kmode value is ignored and the system
call only accepts the hardcoded path.

I've asked you repeatedly to review with me before you change my code.

Best regards,
Alex Ionescu
