From 2daace78a8c94e2cd20164b8efc18171c56e92ec Mon Sep 17 00:00:00 2001 From: Dong Jia Shi Date: Thu, 6 Jul 2017 04:00:45 +0200 Subject: s390: chp: handle CRW_ERC_INIT for channel-path status change When channel path is identified as the report source code (RSC) of a CRW, and initialized (CRW_ERC_INIT) is recognized as the error recovery code (ERC) by the channel subsystem, it indicates a "path has come" event. Let's handle this case in chp_process_crw().
