Hi Ronak,
Thank you for the patch.
What is the fixed from user perspective, what is the impact.
I can see two commands effected from missing enum, they are GET_DCR0_REG
& GET_MAX_CAPABILITIES.
Was user not able to read capabilities, or get random capabilities, from
device up until now?
If so what were these capabilities and how user impacted from missing them?
Can you please detail the impact more in the commit log?
