NTB: fix possible name leak in ntb_register_device()

2024-03-26T22:17:06Z

[ Upstream commit aebfdfe39b9327a3077d0df8db3beb3160c9bdd0 ] If device_register() fails in ntb_register_device(), the device name allocated by dev_set_name() should be freed. As per the comment in device_register(), callers should use put_device() to give up the reference in the error path. So fix this by calling put_device() in the error path so that the name can be freed in kobject_cleanup(). As a result of this, put_device() in the error path of ntb_register_device() is removed and the actual error is returned.

linux/pci.h defines the IRQ flags PCI_IRQ_INTX, PCI_IRQ_MSI and PCI_IRQ_MSIX. Let's use these flags directly instead of the endpoint definitions provided by enum pci_epc_irq_type. This removes the need for defining this enum type completely.
