This is a mostly-automated fixup using Comby (https://comby.dev) to remove lexically-obvious redundant error checks. No functional changes are intended. To reproduce the core change: # Collapse redundant error check conditionals % comby -in-place 'if err != nil { return err } return nil' 'return err' .go # Fold out unnecessary error temporaries % comby -in-place ':[spc~^\s*]err :[~:?]= :[any] return err' ':[spc]return :[any]' .go Fixes #6479 and related cases.
