usb: musb: ux500: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

usb: musb: Set the DT node on the child device The musb glue drivers just copy the glue resources to the musb child device. Instead, set the musb child device's DT node pointer to the parent device's node so that platform_get_irq_byname() can find the resources in the DT. This removes the need for statically populating the IRQ resources from the DT which has been deprecated for some time.

USB: musb: Remove redundant license text Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/ It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: musb: ux500: Fix NULL pointer dereference at system PM The commit 7d32cdef5356 ("usb: musb: fail with error when no DMA controller set"), caused the core platform driver to correctly return an error code when fail probing. Unfurtante it also caused bug for a NULL pointer dereference, during system suspend for the ux500 driver. The reason is a lacking validation of the corresponding ->driver_data pointer, which won't be set when the musb core driver fails to probe (or haven't yet been probed).

usb: musb: ux500: don't propagate the OF node There is a regression in the upcoming v3.16-rc1, that is caused by a problem that has been around for a while but now finally hangs the system. The bootcrawl looks like this: pinctrl-nomadik soc:pinctrl: pin GPIO256_AF28 already requested by a03e0000.usb_per5; cannot claim for musb-hdrc.0.auto pinctrl-nomadik soc:pinctrl: pin-256 (musb-hdrc.0.auto) status -22 pinctrl-nomadik soc:pinctrl: could not request pin 256 (GPIO256_AF28) from group usb_a_1 on device pinctrl-nomadik musb-hdrc musb-hdrc.0.auto: Error applying setting, reverse things back HS USB OTG: no transceiver configured musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -517 platform musb-hdrc.0.auto: Driver musb-hdrc requests probe deferral (...) The ux500 MUSB driver propagates the OF node to the dynamically created musb-hdrc device, which is incorrect as it makes the OF core believe there are two devices spun from the very same DT node, which confuses other parts of the device core, notably the pin control subsystem, which will try to apply all the pin control settings also to the HDRC device as it gets instantiated. (The OMAP2430 for example, does not set the of_node member.)

usb: musb: remove generic_interrupt This patch is based on the discussion of a previous patch to fix an issue where the omap2430 musb driver is not working for N9/N950. Moving all the interrupt handling to the devices. Avoids inclusion of generic interrupt and breakage due to sometimes misleading CONFIG options. This makes sure usb always works if on of the subdrivers is chosen. Tested on Nokia N9/N950. Partially clean up CONFIG_SOC_OMAP3430 which is not necessary in the cases where I removed it. Also helps with the removal work of those options that Tony Lindgren predicted would happen at some point.

usb: musb: remove hand-crafted id handling This replaced the handcrafted id handling by the PLATFORM_DEVID_AUTO value which should do the same thing. This patch probably also fixes ux500 because I did not find the "musbid" variable to remove. And we close a tiny-unlikely race window becuase the old code gave the id back before device was destroyed in the remove case.

usb: musb: ux500: use platform_device_unregister in ux500_remove() platform_device_unregister() only calls platform_device_del() and platform_device_put(), thus use platform_device_unregister() to simplify the code. Also the documents in platform.c shows that platform_device_del and platform_device_put must _only_ be externally called in error cases. All other usage is a bug. dpatch engine is used to auto generate this patch.

usb: musb: make modules behave better There's really no point in doing all that initcall trickery when we can safely let udev handle module probing for us. Remove all of that trickery, by moving everybody to module_init() and making proper use of platform_device_register() rather than platform_device_probe().
