Included check for TPGS bit before proceeding further. The match function was introduced by commit 6c3633d08acf514e2e89aa95d2346ce9d64d719a Signed-off-by: Babu Moger Acked-by: Hannes Reinecke Signed-off-by: James Bottomley --- drivers/scsi/device_handler/scsi_dh_emc.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'drivers') diff --git a/drivers/scsi/device_handler/scsi_dh_emc.c b/drivers/scsi/device_handler/scsi_dh_emc.c index 591186cf189..e1c8be06de9 100644 --- a/drivers/scsi/device_handler/scsi_dh_emc.c +++ b/drivers/scsi/device_handler/scsi_dh_emc.c @@ -629,6 +629,24 @@ static const struct scsi_dh_devlist clariion_dev_list[] = { {NULL, NULL}, }; +static bool clariion_match(struct scsi_device *sdev) +{ + int i; + + if (scsi_device_tpgs(sdev)) + return false; + + for (i = 0; clariion_dev_list[i].vendor; i++) { + if (!strncmp(sdev->vendor, clariion_dev_list[i].vendor, + strlen(clariion_dev_list[i].vendor)) && + !strncmp(sdev->model, clariion_dev_list[i].model, + strlen(clariion_dev_list[i].model))) { + return true; + } + } + return false; +} + static int clariion_bus_attach(struct scsi_device *sdev); static void clariion_bus_detach(struct scsi_device *sdev); @@ -642,6 +660,7 @@ static struct scsi_device_handler clariion_dh = { .activate = clariion_activate, .prep_fn = clariion_prep_fn, .set_params = clariion_set_params, + .match = clariion_match, }; static int clariion_bus_attach(struct scsi_device *sdev) -- cgit v1.2.3-70-g09d2
