Commit Message

Breno Leitao Aug. 8, 2024, 12:25 p.m. UTC 
Update variable names from err to ret in cases where the variable may
return non-error values.

This change facilitates a forthcoming patch that relies on ret being
used consistently to handle return values, regardless of whether they
indicate an error or not.
