From bba79fee7a54ff5351fa36cb324d16b108a7ca06 Mon Sep 17 00:00:00 2001 From: Jeffrey Hugo Date: Mon, 21 Oct 2019 07:18:27 -0700 Subject: Revert "Bluetooth: hci_qca: Add delay for wcn3990 stability" 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.
