Steffen Maier e3c914631c scsi: zfcp: drop default switch case which might paper over missing case ... [ Upstream commit 0c902936e5 ] This was introduced with v4.18 commit 8c3d20aada ("scsi: zfcp: fix missing REC trigger trace for all objects in ERP_FAILED") but would now suppress helpful -Wswitch compiler warnings when building with W=1 such as the following forced example: drivers/s390/scsi/zfcp_erp.c: In function 'zfcp_erp_handle_failed': drivers/s390/scsi/zfcp_erp.c:126:2: warning: enumeration value 'ZFCP_ERP_ACTION_REOPEN_PORT_FORCED' not handled in switch [-Wswitch] switch (want) { ^~~~~~ But then again, only with W=1 we would notice unhandled enum cases. Without the default cases and a missed unhandled enum case, the code might perform unforeseen things we might not want... As of today, we never run through the removed default case, so removing it is no functional change. In the future, we never should run through a default case but introduce the necessary specific case(s) to handle new functionality.
