Subject: [PATCH 5/9] apm32: remove paravirt_enabled() use
Date: Fri, 19 Feb 2016 05:08:32 -0800
Message-ID: <1455887316-9223-6-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1455887316-9223-1-git-send-email-mcgrof@kernel.org>

There is already a check for apm_info.bios == 0, the
apm_info.bios is set from the boot_params.apm_bios_info.
Both Xen and lguest, which are also the only ones that set
paravirt_enabled to true) do never set the apm_bios_info,
the paravirt_enabled() check is simply not needed.
