Subject: [PATCH] cxl/acpi: Return 'rc' instead of '0' in cxl_parse_cfmws()
References: bsc#1012628
Patch-mainline: 6.4.8
Git-commit: 91019b5bc7c2c5e6f676cce80ee6d12b2753d018

[ Upstream commit 91019b5bc7c2c5e6f676cce80ee6d12b2753d018 ]

Driver initialization returned success (return 0) even if the
initialization (cxl_decoder_add() or acpi_table_parse_cedt()) failed.

Return the error instead of swallowing it.
