Some gadget/function drivers might want to do improper request recycling by allocating a single request from one particular endpoint and queueing it to another completely unrelated endpoint. One such case was found with f_loopback.c. To prevent such cases from happening again, let's WARN() so we get a loud enough failure and persuade users to report errors.

USB gadgets composed with configfs lack suspend and resume methods. This patch uses composite_suspend()/composite_resume() the same way e.g. composite_setup() or composite_disconnect() are used in a configfs-based gadget.

This NULL check sets off a static checker warning because we already dereferenced "card" earlier in the function. However, since "card" is never NULL so we can just remove the check. Signed-off-by: NDan Carpenter <dan.carpenter@oracle.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

when disconnecting from host using our soft_connect sysfs interface, also let the gadget driver know about it by calling the gadget driver's ->disconnect() method. No problems have been found while not calling ->disconnect() so far, it's just good convention. Signed-off-by: NFelipe Balbi <balbi@ti.com>

Using ->prepare()/->complete() to mask/unmask IRQs is wrong at least for dwc3. We need to make sure that by the end of ->resume(), IRQs are working and ready to fire because a child device may need working IRQs for its own ->resume() method. Signed-off-by: NFelipe Balbi <balbi@ti.com>
-
由 George Cherian 提交于
Enabling the core interrupts in complete is too late for XHCI, and stops it from proper operation. The root of the problem is due to a disagreement between dwc3-omap and XHCI about when IRQs should be enabled. As it turns out, ->resume's documentation states that: "... generally the driver is expected to start working again, responding to hardware events and software requests (the device itself may be left in a low-power state, waiting for a runtime resume to occur) ..." From that we infer that IRQs must be unmasked by the end of ->resume(). Due to that, we will remove ->prepare() and ->complete() and disable/enable interrupts in ->suspend()/->resume().

Convert the mach info, and store the udc_command in the pxa_udc control structure. It is to be noticed that the udc_is_connected() in mach info is not transfered. This was not used, as mioa701 machine doesn't need it, balloon3 doesn't really use it, and most importantly the current driver never uses it.

In case we unload a gadget driver while any of os_desc_req or req are still pending, we need to make sure to dequeue them. By using our setup_pending and os_desc_pending flags we achieve that in a way that doesn't cause any regressions because we won't dequeue a request which was already completed. The original idea came from Li Jun's commit f2267089 (usb: gadget: composite: dequeue cdev->req before free it in composite_dev_cleanup) which, unfortunately, caused two regressions (kfree() being called before usb_ep_dequeue() and calling usb_ep_dequeue() when the request was already completed). That commit also didn't take care of os_desc_req which can fall into the same situation so we must care for that one too. Note that in order to make code slightly easier to read, we introduce composite_ep_queue() which hides details about how to fiddle with our pending flags. Signed-off-by: NFelipe Balbi <balbi@ti.com>

DWC3's GUID register is supposed to be used to write any sort of version we might want. It helps when getting bug reports for platforms you don't have HW to know which kernel version of the driver was running on the platform. Because we don't really track driver version, but we _do_ track the kernel version, let's write LINUX_VERSION_CODE to that register and use it for debugging.

Pull MTD fixes from Brian Norris: "Three main MTD fixes for 3.18: - A regression from 3.16 which was noticed in 3.17. With the restructuring of the m25p80.c driver and the SPI NOR library framework, we omitted proper listing of the SPI device IDs. This means m25p80.c wouldn't auto-load (modprobe) properly when built as a module. For now, we duplicate the device IDs into both modules. - The OMAP / ELM modules were depending on an implicit link ordering. Use deferred probing so that the new link order (in 3.18-rc) can still allow for successful probing. - Fix suspend/resume support for LH28F640BF NOR flash" * tag 'for-linus-20141102' of git://git.infradead.org/linux-mtd: mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chips mtd: omap: fix mtd devices not showing up mtd: m25p80,spi-nor: Fix module aliases for m25p80 mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id mtd: m25p80: get rid of spi_get_device_id

The sk_prot is irda's own set of protocol handlers, so irda should statically know what that function is anyway, without using an indirect pointer. And as it happens, we know *exactly* what that pointer is statically: it's NULL, because irda doesn't define a disconnect operation. So calling that function is doubly wrong, and will just cause an oops.
