# This is a BitKeeper generated patch for the following project:
# Project Name: Linux kernel tree
# This patch format is intended for GNU patch command version 2.5 or higher.
# This patch includes the following deltas:
# ChangeSet 1.1421 -> 1.1422
# drivers/pnp/support.c 1.4 -> 1.5
#
# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 03/06/18 ambx1@neo.rr.com 1.1422
# [PNP] Important Resource Parsing Fixes
#
# In some cases, we're reading the wrong bits for large tags. This patch corrects
# the issue by setting the affected bits forward by an offset of 2 (skipping over
# the size portion of the tag).
