From 9a12dd6f186c26798f999877be6b02fcd0e65c13 Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Fri, 13 Nov 2020 18:52:16 +0200 Subject: [PATCH] net: phy: lxt: remove the use of .ack_interrupt() In preparation of removing the .ack_interrupt() callback, we must replace its occurrences (aka phy_clear_interrupt), from the 2 places where it is called from (phy_enable_interrupts and phy_disable_interrupts), with equivalent functionality. This means that clearing interrupts now becomes something that the PHY driver is responsible of doing, before enabling interrupts and after clearing them. Make this driver follow the new contract.
