Subject: [PATCH 4.19 076/116] Revert "r8169: check that Realtek PHY driver module is loaded"

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

This reverts commit 85a19b0e31e256e77fd4124804b9cec10619de5e which is
commit f325937735498afb054a0195291bbf68d0b60be5 upstream.

Heiner writes:
	commit 85a19b0e31e2 ("r8169: check that Realtek PHY driver
	module is loaded") made it accidentally to 4.19 and causes an
	issue with Android/x86.  Could you please revert it?
