From 00565cff01262c888512bffe9d41e4831a6f2cc7 Mon Sep 17 00:00:00 2001 From: Yuesong Li Date: Fri, 30 Aug 2024 11:16:42 +0800 Subject: [PATCH] dm: Convert to use ERR_CAST() Use ERR_CAST() as it is designed for casting an error pointer to another type. This macro utilizes the __force and __must_check modifiers, which instruct the compiler to verify for errors at the locations where it is employed.
