usb: musb: sunxi: Switch to use dev_err_probe() helper

2022-09-27T08:36:07Z

In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs. It's more simple in error path.

usb: musb: Fix musb_gadget.c rxstate overflow bug

2022-09-22T13:52:30Z

The usb function device call musb_gadget_queue() adds the passed request to musb_ep::req_list,If the (request->length > musb_ep->packet_sz) and (is_buffer_mapped(req) return false),the rxstate() will copy all data in fifo to request->buf which may cause request->buf out of bounds. Fix it by add the length check : fifocnt = min_t(unsigned, request->length - request->actual, fifocnt); Signed-off-by: Robin Guo Link: https://lore.kernel.org/r/20220906102119.1b071d07a8391ff115e6d1ef@inspur.com Signed-off-by: Greg Kroah-Hartman

musb: fix USB_MUSB_TUSB6010 dependency

2022-08-18T14:33:06Z

Turning on NOP_USB_XCEIV as builtin broke the TUSB6010 driver because of an older issue with the depencency. It is not necessary to forbid NOP_USB_XCEIV=y in combination with USB_MUSB_HDRC=m, but only the reverse, which causes the link failure from the original Kconfig change. Use the correct dependency to still allow NOP_USB_XCEIV=n or NOP_USB_XCEIV=y but forbid NOP_USB_XCEIV=m when USB_MUSB_HDRC=m to fix the multi_v7_defconfig for tusb.

Merge tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

2022-08-05T16:41:12Z

Pull tracing updates from Steven Rostedt: - Runtime verification infrastructure This is the biggest change here. It introduces the runtime verification that is necessary for running Linux on safety critical systems. It allows for deterministic automata models to be inserted into the kernel that will attach to tracepoints, where the information on these tracepoints will move the model from state to state. If a state is encountered that does not belong to the model, it will then activate a given reactor, that could just inform the user or even panic the kernel (for which safety critical systems will detect and can recover from). - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be confused with "work in progress"), and Wakeup While Not Running (WWNR). - Added __vstring() helper to the TRACE_EVENT() macro to replace several vsnprintf() usages that were all doing it wrong. - eprobes now can have their event autogenerated when the event name is left off. - The rest is various cleanups and fixes. * tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (50 commits) rv: Unlock on error path in rv_unregister_reactor() tracing: Use alignof__(struct {type b;}) instead of offsetof() tracing/eprobe: Show syntax error logs in error_log file scripts/tracing: Fix typo 'the the' in comment tracepoints: It is CONFIG_TRACEPOINTS not CONFIG_TRACEPOINT tracing: Use free_trace_buffer() in allocate_trace_buffers() tracing: Use a struct alignof to determine trace event field alignment rv/reactor: Add the panic reactor rv/reactor: Add the printk reactor rv/monitor: Add the wwnr monitor rv/monitor: Add the wip monitor rv/monitor: Add the wip monitor skeleton created by dot2k Documentation/rv: Add deterministic automata instrumentation documentation Documentation/rv: Add deterministic automata monitor synthesis documentation tools/rv: Add dot2k Documentation/rv: Add deterministic automaton documentation tools/rv: Add dot2c Documentation/rv: Add a basic documentation rv/include: Add instrumentation helper functions rv/include: Add deterministic automata monitor definition via C macros ...

usb: musb: tracing: Use the new __vstring() helper

2022-07-19T15:20:24Z

Instead of open coding a __dynamic_array() with a fixed length (which defeats the purpose of the dynamic array in the first place). Use the new __vstring() helper that will use a va_list and only write enough of the string into the ring buffer that is needed.
