Re: [PATCH] Bluetooth: btmtk: Disable remote wakeup for MT7922/MT7925

[Chris Lu (陸稚泓)]

Hi Luiz,

Could we revert this change?

Sorry, MediaTek wasn't aware someone submitted this change and it had
already been merged.

MTK believes this issue is strongly related to the platform's USB hub
behavior, The product lines MTK directly support haven't reported such
issue. 

Disable wake capability would severely impact wake on Bluetooth on
MTK's official product lines. Furthermore, this patch looks like a
workaround. There should be a better way to handle this issue. We hope
this change can be reverted.
