From: Bjorn Helgaas Date: Sat, 21 Apr 2018 19:35:42 +0000 (-0500) Subject: sparc/PCI: Use dev_printk() when possible X-Git-Tag: v4.18-rc1~106^2~15^2 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=adedc05e938fada9c39c89bdea80217355fce6e8;p=uclinux-h8%2Flinux.git sparc/PCI: Use dev_printk() when possible Use the pci_info() and pci_err() wrappers for dev_printk() when possible. Log PCI device vendor and device IDs and BAR information in the same format used by other architectures.
