From e76bb4ee92dc6b4f21eb13d79b5c190b2e5a97e5 Mon Sep 17 00:00:00 2001 From: Sangwook Shin Date: Mon, 18 Aug 2025 11:18:22 +0900 Subject: [PATCH] watchdog: s3c2410_wdt: Replace hardcoded values with macro definitions Modify the code to utilize macro-defined values instead of hardcoded values. The value 0x100 in the s3c2410wdt_set_heartbeat function represents S3C2410_WTCON_PRESCALE_MAX + 1, but it is hardcoded, making its meaning difficult to understand and reducing code readability.
