| | | | | | | | | | | | | | | | | | | | | | The blamed commit made ffs_func_disable() always return -EINVAL as the method calls ffs_func_set_alt() with the ``alt`` argument being ``(unsigned)-1``, which is always greater than MAX_ALT_SETTINGS. Use the MAX_ALT_SETTINGS check just in the f->set_alt() code path, f->disable() doesn't care about the ``alt`` parameter. Make a surgical fix, but really the f->disable() code shall be pulled out from ffs_func_set_alt(), the code will become clearer. A patch will follow. Note that ffs_func_disable() always returning -EINVAL made pixel6 crash on USB disconnect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver is intended as a "client" end of the console connection. When connected to a host it's supposed to receive debug logs, and possibly allow to interact with whatever debug console is available there. Feeding messages back, depending on a configuration may cause log messages be executed as shell commands (which can be really bad if one is unlucky, imagine a log message like "prevented running `rm -rf /home`"). In case of Xen, it exposes sysrq-like debug interface, and feeding it its own logs will pretty quickly hit 'R' for "instant reboot". Contrary to a classic serial console, the USB one cannot be configured ahead of time, as the device shows up only when target OS is up. And at the time device is opened to execute relevant ioctl, it's already too late, especially when logs start flowing shortly after device is initialized. Avoid the issue by changing default to no echo for this type of devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit aba3a8d01d62 ("usb: gadget: u_serial: add suspend resume callbacks") added started_delayed flag, so that new ports which are opened after USB suspend can start IO while resuming.

Yet these two parameters are used by a few drivers, and this can be considered misuse or at least bad practice. Now that the kernel uses C11 to build, these two parameters can be avoided by declaring them internally, thus changing this pattern: struct property *prop; const __be32 *p; u32 val; of_property_for_each_u32(np, "xyz", prop, p, val) { ... } to this: u32 val; of_property_for_each_u32(np, "xyz", val) { ... } However two variables cannot be declared in the for clause even with C11, so declare one struct that contain the two variables we actually need. As the variables inside this struct are not meant to be used by users of this macro, give the struct instance the noticeable name "_it" so it is visible during code reviews, helping to avoid new code to use it directly. Most usages are trivially converted as they do not use those two parameters, as expected. The non-trivial cases are: - drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway - drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the checks had to be replicated in a different way, making code more verbose and somewhat uglier, but I refrained from a full rework to keep as much of the original code untouched having no hardware to test my changes All the changes have been build tested. The few for which I have the hardware have been runtime-tested too.

It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory.

Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

By using the number of bytes written as the limit for scnprintf() it is guaranteed that the final character in the buffer will be overwritten. This is expected if it is a newline but is undesirable when a string is written "as-is" (as libusbgx does, for example). Update the store function to strip an optional newline, matching the behaviour of usb_string_copy().

When CCI is enabled in the design, DWC3 core GSBUSCFG0 cache bits must be updated to support CCI enabled transfers in USB. To program GSBUSCFG0 cache bits create a software node property in AMD-xilinx dwc3 glue driver and pass it to dwc3 core. The core then reads this property value and configures it in dwc3_core_init() sequence.

As a consequence, the default protocol always resulted in MIDI1. This patch addresses the misunderstanding of the protocol handling.
