2019-08-21net: cpsw: fix NULL pointer exception in the probe error pathAntoine Tenart
In certain cases when the probe function fails the error path calls cpsw_remove_dt() before calling platform_set_drvdata(). This is an issue as cpsw_remove_dt() uses platform_get_drvdata() to retrieve the cpsw_common data and leds to a NULL pointer exception. This patches fixes it by calling platform_set_drvdata() earlier in the probe.

2019-08-21usb: chipidea: udc: don't do hardware access if gadget has stoppedPeter Chen
After _gadget_stop_activity is executed, we can consider the hardware operation for gadget has finished, and the udc can be stopped and enter low power mode. So, any later hardware operations (from usb_ep_ops APIs or usb_gadget_ops APIs) should be considered invalid, any deinitializatons has been covered at _gadget_stop_activity. I meet this problem when I plug out usb cable from PC using mass_storage gadget, my callstack like: vbus interrupt->.vbus_session-> composite_disconnect ->pm_runtime_put_sync(&_gadget->dev), the composite_disconnect will call fsg_disable, but fsg_disable calls usb_ep_disable using async way, there are register accesses for usb_ep_disable. So sometimes, I get system hang due to visit register without clock, sometimes not. The Linux Kernel USB maintainer Alan Stern suggests this kinds of solution.

strict module rwx We should keep the case of "#define debug_align(X) (X)" for all arches without CONFIG_HAS_STRICT_MODULE_RWX ability, which would save people, who are sensitive to system size, a lot of memory when using modules, especially for embedded systems.

2019-08-21Revert "cfg80211: fix processing world regdomain when non modular"Hodaszi, Robert
This reverts commit 96cce12ff6e0 ("cfg80211: fix processing world regdomain when non modular"). Re-triggering a reg_process_hint with the last request on all events, can make the regulatory domain fail in case of multiple WiFi modules. On slower boards (espacially with mdev), enumeration of the WiFi modules can end up in an intersected regulatory domain, and user cannot set it with 'iw reg set' anymore. This is happening, because: - 1st module enumerates, queues up a regulatory request - request gets processed by __reg_process_hint_driver(): - checks if previous was set by CORE -> yes - checks if regulator domain changed -> yes, from '00' to e.g. 'US' -> sends request to the 'crda' - 2nd module enumerates, queues up a regulator request (which triggers the reg_todo() work) - reg_todo() -> reg_process_pending_hints() sees, that the last request is not processed yet, so it tries to process it again. __reg_process_hint driver() will run again, and: - checks if the last request's initiator was the core -> no, it was the driver (1st WiFi module) - checks, if the previous initiator was the driver -> yes - checks if the regulator domain changed -> yes, it was '00' (set by core, and crda call did not return yet), and should be changed to 'US' ------> __reg_process_hint_driver calls an intersect Besides, the reg_process_hint call with the last request is meaningless since the crda call has a timeout work. If that timeout expires, the first module's request will lost.

2019-08-21dma-direct: fix zone selection after an unaddressable CMA allocationChristoph Hellwig
The new dma_alloc_contiguous hides if we allocate CMA or regular pages, and thus fails to retry a ZONE_NORMAL allocation if the CMA allocation succeeds but isn't addressable. That means we either fail outright or dip into a small zone that might not succeed either. Thanks to Hillf Danton for debugging this issue.

2019-08-20net/smc: make sure EPOLLOUT is raisedJason Baron
Currently, we are only explicitly setting SOCK_NOSPACE on a write timeout for non-blocking sockets. Epoll() edge-trigger mode relies on SOCK_NOSPACE being set when -EAGAIN is returned to ensure that EPOLLOUT is raised. Expand the setting of SOCK_NOSPACE to non-blocking sockets as well that can use SO_SNDTIMEO to adjust their write timeout. This mirrors the behavior that Eric Dumazet introduced for tcp sockets.

2019-08-20infiniband: hfi1: fix memory leaksWenwen Wang
In fault_opcodes_write(), 'data' is allocated through kcalloc(). However, it is not deallocated in the following execution if an error occurs, leading to memory leaks. To fix this issue, introduce the 'free_data' label to free 'data' before returning the error.
