2018-05-30Input: ti_am335x_tsc - prevent system suspend when TSC is in useGrygorii Strashko
Prevent system suspend while user has finger on touch screen, because TSC is wakeup source and suspending device while in use will result in failure to disable the module. This patch uses pm_stay_awake() and pm_relax() APIs to prevent and resume system suspend as required.

2018-05-30Input: ti_am335x_tsc - ack pending IRQs at probe and before suspendGrygorii Strashko
It is seen that just enabling the TSC module triggers a HW_PEN IRQ without any interaction with touchscreen by user. This results in first suspend/resume sequence to fail as system immediately wakes up from suspend as soon as HW_PEN IRQ is enabled in suspend handler due to the pending IRQ. Therefore clear all IRQs at probe and also in suspend callback for sanity.

2018-05-30qtnfmac: fix invalid STA state on EAPOL failureSergey Matyukevich
Driver switches vif sta_state into QTNF_STA_CONNECTING when cfg80211 core initiates connect procedure. Further this state is changed either to QTNF_STA_CONNECTED or to QTNF_STA_DISCONNECTED by BSS_JOIN and BSS_LEAVE events from firmware. However it is possible that no such events will be sent by firmware, e.g. if EAPOL timed out. In this case vif sta_mode will remain in QTNF_STA_CONNECTING state and all subsequent connection attempts will fail with -EBUSY error code. Fix this by perfroming STA state transition from QTNF_STA_CONNECTING to QTNF_STA_DISCONNECTED in cfg80211 disconnect callback. No need to rely upon firmware events in this case.

2018-05-30nbd: clear DISCONNECT_REQUESTED flag once disconnection occurs.Kevin Vigor
When a userspace client requests a NBD device be disconnected, the DISCONNECT_REQUESTED flag is set. While this flag is set, the driver will not inform userspace when a connection is closed. Unfortunately the flag was never cleared, so once a disconnect was requested the driver would thereafter never tell userspace about a closed connection. Thus when connections failed due to timeout, no attempt to reconnect was made and eventually the device would fail. Fix by clearing the DISCONNECT_REQUESTED flag (and setting the DISCONNECTED flag) once all connections are closed.

2018-05-30net: ethernet: freescale: fix false-positive string overflow warningArnd Bergmann
While compile-testing on arm64 with gcc-8.1, I ran into a build diagnostic: drivers/net/ethernet/freescale/fec_main.c: In function 'fec_probe': drivers/net/ethernet/freescale/fec_main.c:3517:25: error: '%d' directive writing between 1 and 10 bytes into a region of size 5 [-Werror=format-overflow=] sprintf(irq_name, "int%d", i); ^~ drivers/net/ethernet/freescale/fec_main.c:3517:21: note: directive argument in the range [0, 2147483646] sprintf(irq_name, "int%d", i); ^~~~~~~ drivers/net/ethernet/freescale/fec_main.c:3517:3: note: 'sprintf' output between 5 and 14 bytes into a destination of size 8 sprintf(irq_name, "int%d", i); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ It appears this has never shown on ppc32 or arm32 for an unknown reason, but now gcc fails to identify that the 'irq_cnt' loop index has an upper bound of 3, and instead uses a bogus range. To work around the warning, this changes the sprintf to snprintf with the correct buffer length.

2018-05-30tpm: fix race condition in tpm_common_write()Tadeusz Struk
There is a race condition in tpm_common_write function allowing two threads on the same /dev/tpm<N>, or two different applications on the same /dev/tpmrm<N> to overwrite each other commands/responses. Fixed this by taking the priv->buffer_mutex early in the function. Also converted the priv->data_pending from atomic to a regular size_t type. There is no need for it to be atomic since it is only touched under the protection of the priv->buffer_mutex.

2018-05-30PCI: Enable PCI_DOMAINS along with generic PCI host controllerJan Kiszka
The generic PCI host controller is often instantiated by hypervisors, and they may add several of them or add them in addition to a physical host controller like the Jailhouse hypervisor is doing. Therefore, allow for multiple domains so that we can handle them all. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
