From b3546c97c7bb89294fc3da2718b3fabe7ee4c579 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Fri, 4 May 2012 14:17:06 +0200 Subject: [PATCH] usb:hsotg:samsung: Remove Disconnect Interrupt handler The USB Disconnect Interrupt handler, according to specification, is only working at HOST mode. Samsung SoCs (e.g. Exynos4) are working at device mode, so this interrupt is never caught.
