Subject: [PATCH 1/3] hw/cxl/cxl-cdat: Make ct3_load_cdat() return boolean
Date: Thu, 18 Apr 2024 18:04:31 +0800	[thread overview]
Message-ID: <20240418100433.1085447-2-zhao1.liu@linux.intel.com> (raw)
In-Reply-To: <20240418100433.1085447-1-zhao1.liu@linux.intel.com>

From: Zhao Liu <zhao1.liu@intel.com>

As error.h suggested, the best practice for callee is to return
something to indicate success / failure.

So make ct3_load_cdat() return boolean, and this is the preparation for
cxl_doe_cdat_init() returning boolean.
