From b5718b5aeff1930ab06efe5683b54f1a3b2795fb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 10 Nov 2016 15:03:01 +0100 Subject: [PATCH] net: phy: marvell: optimize logic for page changing during init MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of remembering if the page was changed, just compare the current page to the saved one. This is easier and has the advantage to save a register write if the page was already restored. Signed-off-by: Uwe Kleine-König Reviewed-by: Florian Fainelli Signed-off-by: David S.
