Subject: [PATCH] shpchp: remove redundant display of PCI device resources
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7e88ed199689f333668b62348051202706b6a74a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] shpchp: remove redundant display of PCI device resources

Info about resources assigned to PCI devices is already available
through sysfs and pci utilities. There's no need for shpchp to
create another sysfs file to display the same information.
