From 550bc517e59347b3b1af7d290eac4fb1411a3d4e Mon Sep 17 00:00:00 2001 From: Qianfeng Rong Date: Sun, 17 Aug 2025 22:23:27 +0800 Subject: [PATCH] regulator: bd718x7: Use kcalloc() instead of kzalloc() Replace calls of 'devm_kzalloc(dev, count * sizeof([type]), flags)' with 'devm_kcalloc(dev, count, sizeof([type]), flags)' in setup_feedback_loop() for safer memory allocation with built-in overflow protection.
