Subject: [PATCH 4.19 01/99] iwlwifi: fix driver operation for 5350

From: Emmanuel Grumbach <emmanuel.grumbach@...el.com>

commit 5c9adef9789148d382d7d1307c3d6bfaf51d143d upstream.

We introduced a bug that prevented this old device from
working. The driver would simply not be able to complete
the INIT flow while spewing this warning:

 CSR addresses aren't configured
 WARNING: CPU: 0 PID: 819 at drivers/net/wireless/intel/iwlwifi/pcie/drv.c:917
 iwl_pci_probe+0x160/0x1e0 [iwlwifi]

Cc: stable@...r.kernel.org # v4.18+
Fixes: a8cbb46f831d ("iwlwifi: allow different csr flags for different device families")
