From 822bd5aa2b8e8fa1d328f03bf5b9c75701481bf0 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 14 Nov 2007 17:00:04 -0800 Subject: [PATCH] tle62x0 driver stops ignoring read errors The tle62x0 driver was ignoring all read errors. This patch makes it pass such errors up the stack, instead of returning bogus data.
