Subject: [PATCH 3.18 27/27] Revert "tty: goldfish: Fix a parameter of a call to free_irq"

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

This reverts commit 0961072120f3e40fe98c2bb49c45549ca3f042dc which is
commit 1a5c2d1de7d35f5eb9793266237903348989502b upstream.

Ben writes:
	This fixes a bug introduced in 4.6 by commit 465893e18878 "tty:
	goldfish: support platform_device with id -1".  For earlier
	kernel versions, it *introduces* a bug.

So let's drop it.
