Subject: powerpc/eeh: Show hex prefix for PE state sysfs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2013add4ce73c93ae2148969a9ec3ecc8b1e26fa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

powerpc/eeh: Show hex prefix for PE state sysfs

As Michael suggested, the hex prefix for the output of EEH PE
state sysfs entry (/sys/bus/pci/devices/xxx/eeh_pe_state) is
always informative to users.
