Subject: [PATCH v10 01/17] cxl/pci: Remove unnecessary CXL Endpoint handling helper functions
Date: Thu, 26 Jun 2025 17:42:36 -0500	[thread overview]
Message-ID: <20250626224252.1415009-2-terry.bowman@amd.com> (raw)
In-Reply-To: <20250626224252.1415009-1-terry.bowman@amd.com>

The CXL driver's cxl_handle_endpoint_cor_ras()/cxl_handle_endpoint_ras()
are unnecessary helper functions used only for Endpoints. Remove these
functions as they are not common for all CXL devices and do not provide
value for EP handling.

Rename __cxl_handle_ras to cxl_handle_ras() and __cxl_handle_cor_ras()
to cxl_handle_cor_ras().
