[ Upstream commit 24d413a ] Fix a race which leads to an Oops with NULL pointer dereference. The dereference is in brcmf_config_dongle() when cfg_to_ndev() attempts to get net_device structure of interface with index 0 via if2bss mapping. This shouldn't fail because of check for bus being ready in brcmf_netdev_open(), but it's not synchronised with USB disconnect and there is a race: after the check the bus can be marked down and the mapping for interface 0 may be gone. Solve this by modifying disconnect handling so that the removal of mapping of ifidx to brcmf_if structure happens after netdev removal (which is synchronous with brcmf_netdev_open() thanks to rtln being locked in devinet_ioctl()). This assures brcmf_netdev_open() returns before the mapping is removed during disconnect.

Solve this by modifying disconnect handling so that the removal of mapping of ifidx to brcmf_if structure happens after netdev removal (which is synchronous with brcmf_netdev_open() thanks to rtln being locked in devinet_ioctl()). This assures brcmf_netdev_open() returns before the mapping is removed during disconnect.

[ Upstream commit 24d413a ] Fix a race which leads to an Oops with NULL pointer dereference. The dereference is in brcmf_config_dongle() when cfg_to_ndev() attempts to get net_device structure of interface with index 0 via if2bss mapping. This shouldn't fail because of check for bus being ready in brcmf_netdev_open(), but it's not synchronised with USB disconnect and there is a race: after the check the bus can be marked down and the mapping for interface 0 may be gone. Solve this by modifying disconnect handling so that the removal of mapping of ifidx to brcmf_if structure happens after netdev removal (which is synchronous with brcmf_netdev_open() thanks to rtln being locked in devinet_ioctl()). This assures brcmf_netdev_open() returns before the mapping is removed during disconnect.
