From: Jerome Brunet Date: Tue, 3 Jun 2025 17:03:38 +0000 (+0200) Subject: PCI: endpoint: pci-epf-vntb: Return -ENOENT if pci_epc_get_next_free_bar() fails X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7ea488cce73263231662e426639dd3e836537068;p=thirdparty%2Fkernel%2Flinux.git PCI: endpoint: pci-epf-vntb: Return -ENOENT if pci_epc_get_next_free_bar() fails According the function documentation of epf_ntb_init_epc_bar(), the function should return an error code on error. However, it returns -1 when no BAR is available i.e., when pci_epc_get_next_free_bar() fails. Return -ENOENT instead.
