Subject: x86: xen: platform-pci-unplug: use pr_err() and pr_warn() instead of raw printk()
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=1a0df28c09831dc4bd336fe6e090bbe85a07e79f;p=kernel.git

x86: xen: platform-pci-unplug: use pr_err() and pr_warn() instead of raw printk()

Since we have the nice helpers pr_err() and pr_warn(), use them instead
of raw printk().

[jgross@suse.com] Move the "#define pr_fmt" above the #includes in
                  order to avoid build warnings due to redefinition.
