This is not the good way to write the message. The information it conveys
is "checkpatch generated this warning, so I have made some change
(unspecified) that make checkpatch not complain".
A better approach would be to say:
Declare the file_operations structure ll_file_operations as const, as done
elsewhere in the kernel, as there are no modifications to its fields.
Problem found using checkpatch.
This way the reader knows what was done, and what issues were taken into
account when making the change. At the same time, you still credit
checkpatch for helping you find the problem
