Subject: Re: [PATCH] Bluetooth: btusb: Add Realtek MT7925 support ID
 0x13d3:0x3608

Hi Luiz and Pavel,

I think these is something wrong to the title and content of this
patch. MT7925 is an connectivity IC from Mediatek rather than Realtek.

Although this patch has been accpeted and merged to the next tree, I'm
wondering if the typo can still be fixed? I'm afraid that such error
could cause some misunderstanding to users.

Thanks a lot!

BRs,
Chris
