From b003a4923628d5b0ffbbaeda332bfa1a98776cf1 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 8 Mar 2021 16:24:47 +0100 Subject: [PATCH] PCI: thunder: Fix compile testing [ Upstream commit 16f7ae5906dfbeff54f74ec75d0563bb3a87ab0b ] Compile-testing these drivers is currently broken. Enabling it causes a couple of build failures though: drivers/pci/controller/pci-thunder-ecam.c:119:30: error: shift count >= width of type [-Werror,-Wshift-count-overflow] drivers/pci/controller/pci-thunder-pem.c:54:2: error: implicit declaration of function 'writeq' [-Werror,-Wimplicit-function-declaration] drivers/pci/controller/pci-thunder-pem.c:392:8: error: implicit declaration of function 'acpi_get_rc_resources' [-Werror,-Wimplicit-function-declaration] Fix them with the obvious one-line changes.
