2016-08-22IB/usnic: Fix error return codeChristophe Jaillet1-1/+2

2015-10-21usnic: correctly check failed allocationInsu Yun1-5/+4
Since ib_alloc_device returns allocated memory address, not error, it should be checked as IS_NULL, not IS_ERR_OR_NULL. Signed-off-by: Insu Yun <wuninsu@gmail.com> Reviewed-by: Dave Goodell <dgoodell@cisco.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2015-10-06usnic: add missing clauses to BSD licenseJeff Squyres1-3/+18
The usnic_verbs kernel module was clearly marked with the following in its code: MODULE_LICENSE("Dual BSD/GPL"); However, we accidentally left a few clauses of the BSD text out of the license header in all the source files. This commit fixes that: all the files are properly dual BSD/GPL-licensed. Contributors that might have been confused by this have been contacted to get their permission and are Cc:ed here.

2015-05-20IB/core: Add per port immutable struct to ib_deviceIra Weiny1-0/+17
As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data.

2014-08-12PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine1-1/+1
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
