From: Doug Thompson Date: Thu, 19 Jul 2007 08:50:26 +0000 (-0700) Subject: drivers/edac: fix edac_mc init apis X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b8f6f9755248026f21282e25cac49a1af698056c;p=linux-beck.git drivers/edac: fix edac_mc init apis Refactoring of sysfs code necessitated the refactoring of the edac_mc_alloc() and edac_mc_add_mc() apis, of moving the index value to the alloc() function. This patch alters the in tree drivers to utilize this new api signature. Having the index value performed later created a chicken-and-the-egg issue. Moving it to the alloc() function allows for creating the necessary sysfs entries with the proper index number Cc: Alan Cox alan@lxorguk.ukuu.org.uk Signed-off-by: Doug Thompson Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/drivers/edac/amd76x_edac.c b/drivers/edac/amd76x_edac.c index 1c1e02e59585..f22075410591 100644 --- a/drivers/edac/amd76x_edac.c +++ b/drivers/edac/amd76x_edac.c @@ -238,7 +238,7 @@ static int amd76x_probe1(struct pci_dev *pdev, int dev_idx) debugf0("%s()\n", __func__); pci_read_config_dword(pdev, AMD76X_ECC_MODE_STATUS, &ems); ems_mode = (ems >> 10) & 0x3; - mci = edac_mc_alloc(0, AMD76X_NR_CSROWS, AMD76X_NR_CHANS); + mci = edac_mc_alloc(0, AMD76X_NR_CSROWS, AMD76X_NR_CHANS, 0); if (mci == NULL) { return -ENOMEM; @@ -263,7 +263,7 @@ static int amd76x_probe1(struct pci_dev *pdev, int dev_idx) /* Here we assume that we will never see multiple instances of this * type of memory controller.
