* USB: Fix a bug on appledisplay.c regarding signednesspancho horrillo2009-12-231-2/+2
| | | | | | | | | | | | | | | | brightness status is reported by the Apple Cinema Displays as an 'unsigned char' (u8) value, but the code used 'char' instead. Note that he driver was developed on the PowerPC architecture, where the two types are synonymous, which is not always the case. Fixed that. Otherwise the driver will interpret brightness levels > 127 as negative, and fail to load.

* USB: option: support hi speed for modem Haier CE100Donny Kurnia2009-12-231-0/+5
| | | | | | | | | | | | | | | | | I made this patch for usbserial driver to add the support for EVDO modem Haier CE100. The bugs report for this is here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/490068 This patch based on these post: http://blankblondtank.wordpress.com/2009/09/04/mengoptimalkan-koneksi-modem-haier-ce-100-cdma-di-linux/ http://tantos.web.id/blogs/how-to-internet-connection-using-cdma-evdo-modem-and-karmic-koala-ubuntu-9-10 I hope this patch can help other that have the Haier C100 modem, mostly in my country, Indonesia.

| | | | | | | | | | | | | | Some of these workarounds are already in place, but labeled as affecting all BF52x parts. Since we have official anomaly numbers now, use those defines. And since writing to the FIFO has a similar hang issue as reading from the FIFO, implement the workaround there too when necessary.

* USB: musb: Fix array index out of bounds issueMaulik Mankad2009-12-231-1/+1
| | | | | | | | | | | | | | | | | | | This patch fixes the below array index out of bounds issue. Buffer overflow, array index of 'aInfo' may be out of bounds. Array 'aInfo' of size 78 may use index value(s) 6..84 The data stored in 'aInfo' array exceeds the array size of 78. This patch increases the size of this array to hold the string correctly without any memory corruption. This issue was reported by Klockwork tool.

* USB: emi62: fix crash when trying to load EMI 6|2 firmwareClemens Ladisch2009-12-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | While converting emi62 to use request_firmware(), the driver was also changed to use the ihex helper functions. However, this broke the loading of the FPGA firmware because the code tries to access the addr field of the EOF record which works with a plain array that has an empty last record but not with the ihex helper functions where the end of the data is signaled with a NULL record pointer, resulting in: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62] This can be fixed by changing the loop condition to test the return value of ihex_next_binrec() directly (like in emi26.c).

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1315) fixes some bugs in the USB core authorization code: usb_deauthorize_device() should deallocate the device strings instead of leaking them, and it should invoke usb_destroy_configuration() (which does proper reference counting) instead of freeing the config information directly. usb_authorize_device() shouldn't change the device strings until it knows that the authorization will succeed, and it should autosuspend the device at the end (having autoresumed the device at the start). Because the device strings can be changed, the sysfs routines to display the strings must protect the string pointers by locking the device.

* kfifo: move struct kfifo in placeStefani Seibold2009-12-224-31/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new generic kernel FIFO implementation. The current kernel fifo API is not very widely used, because it has to many constrains. Only 17 files in the current 2.6.31-rc5 used it. FIFO's are like list's a very basic thing and a kfifo API which handles the most use case would save a lot of development time and memory resources. I think this are the reasons why kfifo is not in use: - The API is to simple, important functions are missing - A fifo can be only allocated dynamically - There is a requirement of a spinlock whether you need it or not - There is no support for data records inside a fifo So I decided to extend the kfifo in a more generic way without blowing up the API to much. The new API has the following benefits: - Generic usage: For kernel internal use and/or device driver. - Provide an API for the most use case. - Slim API: The whole API provides 25 functions. - Linux style habit. - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros - Direct copy_to_user from the fifo and copy_from_user into the fifo. - The kfifo itself is an in place member of the using data structure, this save an indirection access and does not waste the kernel allocator. - Lockless access: if only one reader and one writer is active on the fifo, which is the common use case, no additional locking is necessary. - Remove spinlock - give the user the freedom of choice what kind of locking to use if one is required. - Ability to handle records. Three type of records are supported: - Variable length records between 0-255 bytes, with a record size field of 1 bytes. - Variable length records between 0-65535 bytes, with a record size field of 2 bytes. - Fixed size records, which no record size field. - Preserve memory resource. - Performance! - Easy to use! This patch: Since most users want to have the kfifo as part of another object, reorganize the code to allow including struct kfifo in another data structure. This requires changing the kfifo_alloc and kfifo_init prototypes so that we pass an existing kfifo pointer into them. This patch changes the implementation and all existing users.

| * USB: Close usb_find_interface race v3Russ Dill2009-12-151-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB drivers that create character devices call usb_register_dev in their probe function. This associates the usb_interface device with that minor number and creates the character device and announces it to the world. However, the driver's probe function is called before the new usb_interface is added to the driver's klist_devices. This is a problem because userspace will respond to the character device creation announcement by opening the character device. The driver's open function will the call usb_find_interface to find the usb_interface associated with that minor number. usb_find_interface will walk the driver's list of devices and find the usb_interface with the matching minor number. Because the announcement happens before the usb_interface is added to the driver's klist_devices, a race condition exists. A straightforward fix is to walk the list of devices on usb_bus_type instead since the device is added to that list before the announcement occurs. bus_find_device calls get_device to bump the reference count on the found device. It is arguable that the reference count should be dropped by the caller of usb_find_interface instead of usb_find_interface, however, the current users of usb_find_interface do not expect this. The original version of this patch only matched against minor number instead of driver and minor number. This version matches against both.

| | | | | | | | | | | | | | | The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030 for OMAP3. The common modules like RTC, Regulator creates opportunity to re-use the most of the code from twl4030. This patch renames few common drivers twl4030* files to twl* to enable the code re-use.
