Subject: [PATCH] Bluetooth: hci_qca: Refactor error handling in qca_suspend()
Git-commit: 4da385f742d485fe3135a2711299cbf28ea24bc9
Patch-mainline: v5.9-rc1
References: jsc#SLE-13430
If waiting for IBS sleep times out jump to the error handler, this is
easier to read than multiple 'if' branches and a fall through to the
error handler.
