From: Siddharth Shrimali Date: Tue, 10 Mar 2026 12:10:13 GMT Subject: [PATCH] submodule--helper: replace malloc with xmalloc Message-ID: <20260310121013.39291-1-r.siddharth.shrimali@gmail.com> The submodule_summary_callback() function currently uses a raw malloc() which could lead to NULL pointer dereference. Standardize this by replacing malloc() with xmalloc() for error handling. Also, remove the unnecessary type cast and use sizeof(*temp) instead of struct name in xmalloc to improve maintainability of the code.
