Hi GHC devs, I have made a rebase to bring my merge request [ https://gitlab.haskell.org/ghc/ghc/merge_requests/1659] up to date with the current GHC codebase. In the process there were some conflicts (as expected) which I could solve. However, now that I have pushed the result, I get these messages from the CI infrastructure: $ validate-whitespace .git $(git rev-list $base..$CI_COMMIT_SHA) ===================================================================================== commit 0d92f8c898ccbf2ffb602bc75e50e9ffd44811d8 has whitespace linter issues: *ERROR* compiler/typecheck/TcUnify.hs:810: introduces trailing whitespace

Validation FAILED for 465d27f2119d7bdbe06832dd79c3848e27b4aaef ===================================================================================== Validation FAILED because at least one commit had linter errors! What is the right approach to fix these problems? I can fix the whitespace issues in a new commit, but I don't see how to fix them in all the interim commits :( Thanks in advance and kind regards, Alejandro
