From 21e37742361fe408d534c004b6e39717cb6b5999 Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Sat, 27 Aug 2011 11:31:18 -0700 Subject: [PATCH] Staging: hv: storvsc: Handle IDE devices using the storvsc driver Now, enable handling of all IDE devices by extending the storvsc device id table to handle IDE guid. As part of this cleanup Kconfig and Hyper-V Makefile to not build the IDE driver (blkvsc). Signed-off-by: K. Y.
