| |
2.6.25-stable review patch. If anyone has any objections, please let us know.
------------------
From: Jiri Kosina <jkosina@suse.cz>
commit c3a34f4390396a4bede3f8b7bcc5153f50b974bb upstream
This patch introduces i8042_dmi_nopnp_table to make it possible to perform DMI matches for systems that need 'i8042.nopnp' to work correctly, and introduces such an entry for Intel D845PESV -- this system doesn't detect PS2 mouse reliably without this option, as reported by Robert Lewis.
[dtor@mail.ru - make it compile if CONFIG_PNP is off - reported by Randy Dunlap]
