From db48255b32a2664d8b321a51f46084a669e11ac6 Mon Sep 17 00:00:00 2001 From: Henryk Dembkowski Date: Sat, 12 Feb 2011 11:50:09 -0800 Subject: [PATCH] isci: c99 tables cleanup step1 scic_sds_stp_remote_device_ready_substate_handler_table[] scic_sds_smp_remote_device_ready_substate_handler_table[] c99 the struct initializers: 1/ allows grep to consistently show method name associations. The naming is mostly consistent (except when it isn't) so this guarantees coverage of present and future exception cases. 2/ let's the compiler guarantee that the state table array entry correlates with an actual state name and detect accidental reordering or deletion of states. 3/ allows default handler's to be identified easily Signed-off-by: Henryk Dembkowski Signed-off-by: Dan Williams --- .../scsi/isci/core/scic_sds_remote_device.h | 12 +- .../isci/core/scic_sds_smp_remote_device.c | 75 +++--- .../isci/core/scic_sds_stp_remote_device.c | 215 ++++++++---------- 3 files changed, 132 insertions(+), 170 deletions(-) diff --git a/drivers/scsi/isci/core/scic_sds_remote_device.h b/drivers/scsi/isci/core/scic_sds_remote_device.h index aed4eb640c26..d91570f212c6 100644 --- a/drivers/scsi/isci/core/scic_sds_remote_device.h +++ b/drivers/scsi/isci/core/scic_sds_remote_device.h @@ -158,8 +158,6 @@ enum scic_sds_stp_remote_device_ready_substates { * coming to be recovered from certain hardware specific error. */ SCIC_SDS_STP_REMOTE_DEVICE_READY_SUBSTATE_AWAIT_RESET, -
