Subject: [PATCH v3 4/4] PCI: pciehp: Remove pciehp_green_led_{on,off,blink}()
Date:   Mon, 19 Aug 2019 19:06:43 +0300
Message-Id: <20190819160643.27998-5-efremov@linux.com>
In-Reply-To: <20190819160643.27998-1-efremov@linux.com>

Precedence: bulk

Remove pciehp_green_led_{on,off,blink}() and use pciehp_set_indicators()
instead, since the code is mostly the same.
