Subject: x86/PCI: VMD: Set bus resource start to 0
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d068c350c0486ba9011abb6f91cdc0c12b522155;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86/PCI: VMD: Set bus resource start to 0

The bus always starts at 0.  Due to alignment and down-casting, this
happened to work before, but looked alarmingly incorrect in kernel logs.
