[PATCH v1] cxl/port: Convert to use ERR_CAST()
From: Yuesong Li
Date: Thu Aug 29 2024 - 08:56:42 EST
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.
