Subject: [PATCH AUTOSEL 5.4 02/23] PCI: thunder: Fix compile testing
Date: Wed, 12 May 2021 14:03:46 -0400	[thread overview]
Message-ID: <20210512180408.665338-2-sashal@kernel.org> (raw)
In-Reply-To: <20210512180408.665338-1-sashal@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

[ 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.
