| * usb: gadget: rndis: remove the limit of available rndis connectionsAndrzej Pietrasiewicz2015-05-071-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RNDIS function has a limitation on the number of allowed instances. So far it has been RNDIS_MAX_CONFIGS, which happens to be one. In order to eliminate this kind of arbitrary limitation we should not preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params instances but instead allow allocating them on demand. This patch allocates struct rndis_params on demand in rndis_register(). Coversly, the structure is free()'d in rndis_deregister(). If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which is the same behaviour as before, but the moment of creation is delayed until struct rndis_params is actually allocated. rnids_init() and rndis_exit() have nothing to do, so they are eliminated.

* | Documentation usb serial: fixed how to provide vendor and product idH. Nikolaus Schaller2015-05-071-5/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While trying to test a Cinterion GSM/GPS/3G module I had reconfigured the USB interface by mistake and therefore needed to run a different USB driver than CDC-ACM. It turned out that I need the "usbserial" driver. This file is an official description how to use it: Documentation/usb/usb-serial.txt But it is outdated. The parameters vendor= and product= have been superseded by a /sys interface. Here was the solution: https://bbs.archlinux.org/viewtopic.php?id=175499 insmod usbserial vendor=0x#### product=0x#### becomes (first #### is vendor, second is product) modprobe usbserial echo #### #### >/sys/bus/usb-serial/drivers/generic/new_id This patch changes the documentation file to describe the modern variant. Please note that the old one still works (if compiled as module). Signed-off-by: H.

It's a total of 217 non-merge commits with pretty much everything being touched.

After switch to run complete() in tasklet, we will enable local IRQs when calling complete() since we can do it at that time. Even though we still disable IRQs now when calling complete() in tasklet, the URB documentation is updated to claim complete() will be run in tasklet context and local IRQs will be enabled, so that USB drivers can know the change and avoid one deadlock caused by: assume IRQs disabled in complete() and call spin_lock() to hold lock which might be acquired in interrupt context. Current spin_lock() usages in drivers' complete() will be cleaned up at the same time, and once the cleanup is finished, local IRQs will be enabled when calling complete() in tasklet. Also fix description about type of usb_complete_t, and remove the advice of running completion handler in tasklet for decreasing system latency.
