From 0de53be394deefe093b79c3b85f453023173fa98 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Wed, 26 Apr 2023 16:04:44 +0200 Subject: soc/amd/stoneyridge/acpi/sb_pci0_fch: report correct number of PCI buses This ports commit 8c28e51a16e1 ("soc/amd/picasso: fix host bridge bus numbers") back to Stoneyridge so that the correct number of PCI buses gets reported from PCI0's _CRS method.
