[PATCH] Revert "Bluetooth: hci_qca: Add delay for wcn3990 stability"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This reverts commit cde9dde6e11a5ab54b6462cd46d82878926783bc.

The frame reassembly errors were root caused to a transient gpio issue.
The missing response was root caused to an issue with properly managing
RFR in the uart driver.  Addressing those root causes occurs outside of
hci_qca and eliminates the need for the 50ms delay, so remove it.
