Subject: [PATCH v2 03/10] cxl: Rename find_dport() to provide better function intent
Date: Tue,  6 May 2025 17:43:03 -0700	[thread overview]
Message-ID: <20250507004310.3536991-4-dave.jiang@intel.com> (raw)
In-Reply-To: <20250507004310.3536991-1-dave.jiang@intel.com>

Rename find_dport() to find_dport_by_num() to indicate that the function
is trying to match a dport by its hardware number index.

Suggested-by: Dan Williams <dan.j.williams@intel.com>
