Subject: [PATCH RESEND v2 2/2] cpuidle: tegra: Remove do_idle firmware call
Date: Tue,  2 Mar 2021 12:54:05 +0300	[thread overview]
Message-ID: <20210302095405.28453-2-digetx@gmail.com> (raw)
In-Reply-To: <20210302095405.28453-1-digetx@gmail.com>

The do_idle firmware call is unused by all Tegra SoCs, hence remove it in
order to keep driver's code clean.
