Subject: PCI: re-add debug prints for unmodified BARs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=395a125c6237802b19bf22b41017c99ff57f1024;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PCI: re-add debug prints for unmodified BARs

Print out for device BAR values before the kernel tries to update them.
Also make related output use KERN_DEBUG.
