Subject: [PATCH 5.11 158/775] Bluetooth: hci_qca: check for SSR triggered flag while suspend

From: Venkata Lakshmi Narayana Gubba <gubbaven@...eaurora.org>

[ Upstream commit 1bb0c66332babc5cbc4581d962da0b03af9f23e8 ]

QCA_IBS_DISABLED flag will be set after memorydump started from
controller.Currently qca_suspend() is waiting for SSR to complete
based on flag QCA_IBS_DISABLED.Added to check for QCA_SSR_TRIGGERED
flag too.
