Subject: [PATCH v1 3/3] gpio: tegra: Use NOIRQ phase for suspend/resume
Date: Sun, 15 Dec 2019 21:30:47 +0300 [thread overview]
Message-ID: <20191215183047.9414-4-digetx@gmail.com> (raw)
In-Reply-To: <20191215183047.9414-1-digetx@gmail.com>
All GPIO interrupts are disabled during of the NOIRQ suspend/resume
phase, thus there is no need to manually disable the interrupts. This
patch doesn't fix any problem, this is just a minor clean-up.
