From d3cdf4585f2f9122d1165acca40e801c75afa320 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Mon, 5 Dec 2022 12:21:40 -0800 Subject: cxl/acpi: Warn about an invalid CHBCR in an existing CHBS entry After parsing for a CHBCR in cxl_get_chbcr() the case of (ctx.chbcr == CXL_RESOURCE_NONE) is a slighly different error reason than the !ctx.chbcr case. In the first case the CHBS was found but the CHBCR was invalid or something else failed to determine it, while in the latter case no CHBS entry exists at all. Update the warning message to reflect this. The log messages for both cases can be differentiated now and the reason for a failure can be determined better.
