| |
3.2.52-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Lan Tianyu <tianyu.lan@intel.com>
commit 524f42fab787a9510be826ce3d736b56d454ac6d upstream.
The ECDT of ASUSTEK L4R doesn't provide correct command and data I/O ports. The DSDT provides the correct information instead.
For this reason, add this machine to quirk list for ECDT validation and use the EC information from the DSDT.
