Re: [External] Re: [PATCH] WHENCE: Fix ISH firmware symlink prefix for Lenovo PTL systems

Hi Josh,

Thanks for sharing the patch.

After reviewing this, we realized that the incorrect symlink name was introduced from our side. Sorry for this.
This fix correctly help the firmware to be loaded on PTL systems.

We ACK this patch. Please go ahead and accept it.

Thanks @Aaron Ma
