From 6340d61b9005de1fab86963ff38c9cfd66e68483 Mon Sep 17 00:00:00 2001 From: Tamir Duberstein Date: Fri, 7 Mar 2025 06:27:35 -0500 Subject: [PATCH] scanf: remove redundant debug logs Remove `pr_debug` calls which emit information already contained in `pr_warn` calls that occur on test failure. This reduces unhelpful test verbosity. Note that a `pr_debug` removed from `_check_numbers_template` appears to have been the only guard against silent false positives, but in fact this condition is handled in `_test`; it is only possible for `n_args` to be `0` in `_check_numbers_template` if the test explicitly expects it *and* `vsscanf` returns `0`, matching the expectation.
