From fc25f79af321c01a739150ba2c09435cf977a63d Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Mon, 30 Apr 2012 11:57:44 -0700 Subject: [PATCH] isci: fix oem parameter validation on single controller skus OEM parameters [1] are parsed from the platform option-rom / efi driver. By default the driver was validating the parameters for the dual-controller case, but in single-controller case only the first set of parameters may be valid. Limit the validation to the number of actual controllers detected otherwise the driver may fail to parse the valid parameters leading to driver-load or runtime failures. [1] the platform specific set of phy address, configuration,and analog tuning values [stable v3.0+] Cc: Reported-by: Dave Jiang Tested-by: Dave Jiang Signed-off-by: Dan Williams --- drivers/scsi/isci/init.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/scsi/isci/init.c b/drivers/scsi/isci/init.c index fdae42f572b..9e1c83e425e 100644 --- a/drivers/scsi/isci/init.c +++ b/drivers/scsi/isci/init.c @@ -639,7 +639,7 @@ static int __devinit isci_pci_probe(struct pci_dev *pdev, const struct pci_devic if (!orom) orom = isci_request_oprom(pdev); - for (i = 0; orom && i < ARRAY_SIZE(orom->ctrl); i++) { + for (i = 0; orom && i < num_controllers(pdev); i++) { if (sci_oem_parameters_validate(&orom->ctrl[i], orom->hdr.version)) { dev_warn(&pdev->dev, -- 2.41.0
