Hi Andy, Dan, Hans,
Thank you for the review and catching this.
In this v3, I have completely dropped the changes to the debug
parameters to keep the staging debug facilities fully intact as requested.
This patch now strictly focuses on removing the 'pad_w' and 'pad_h'
module parameters and converting them into internal driver constants.
Remove the 'pad_w' and 'pad_h' module parameters to prevent userspace
from overriding internal ISP hardware padding boundaries. Convert them
into internal driver constants instead.
This partially addresses the 'Remove unnecessary/unwanted module
parameters' task in the driver's TODO file, while keeping the debug
facilities intact as requested by maintainers.

This must not be the part of the commit message. See below. > Remove the 'pad_w' and 'pad_h' module parameters to prevent userspace > from overriding internal ISP hardware padding boundaries.

If it partially addresses, then I recommend to finish the task. Half-baked solutions usually are not welcome (only as a discussion starter or so). I already told that the whole debug facility in this driver should be aligned with the kernel APIs and tools.
