The probe does not strictly require the USB_CDC_DMM_TYPE descriptor, which is a good thing as it makes the driver usable on non-conforming interfaces. A user could e.g. bind to it to a CDC ECM interface by using the new_id and bind sysfs files. But this would fail with a 0 buffer length due to the missing descriptor. Fix by defining a reasonable fallback size: The minimum device receive buffer size required by the CDC WMC standard, revision 1.1 Signed-off-by:

This patch (as1515) fixes some unavoidably dumb compiler warnings: CC [M] drivers/usb/renesas_usbhs/mod.o In file included from drivers/usb/host/ohci-hcd.c:101:0: drivers/usb/host/ohci-dbg.c: In function ‘fill_registers_buffer’: drivers/usb/host/ohci-dbg.c:656:2: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress] drivers/usb/host/ohci-dbg.c:675:3: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress] Instead of trying to fix the macro to work under all cirumstances, just add a second macro for use in cases where the "next" argument is the address of a local variable. Unfortunately the macro cannot be replaced by a real subroutine, because there's no va_list version of ohci_dbg() or dev_dbg(). Signed-off-by:

Add missing iounmap in error handling code, in a case where the function already preforms iounmap on some other execution path. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e; statement S,S1; int ret; @@ e = \(ioremap\|ioremap_nocache\)(...) ... when != iounmap(e) if (<+...e...+>) S ... when any when != iounmap(e) *if (...) { ... when != iounmap(e) return ...; } ... when any iounmap(e); // </smpl> Signed-off-by:

[Based on a patch from Johan, mangled by gregkh to keep things in line] Fix up the variable usage in the set_termios call. Signed-off-by:
-
Preston Fick authored
This fix changes the way baudrates are set on the CP210x devices from Silicon Labs. The CP2101/2/3 will respond to both a GET/SET_BAUDDIV command, and GET/SET_BAUDRATE command, while CP2104 and higher devices only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in kernel version 3.2.0 only implements the GET/SET_BAUDDIV command. This patch implements the two new codes for the GET/SET_BAUDRATE commands. Then there is a change in the way that the baudrate is assigned or retrieved. This is done according to the CP210x USB specification in AN571. This document can be found here: http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart Sections 5.3/5.4 describe the USB packets for the old baudrate method. Sections 5.5/5.6 describe the USB packets for the new method. This patch also implements the new request scheme, and eliminates the unnecessary baudrate calculations since it uses the "actual baudrate" method. This patch solves the problem reported for the CP2104 in bug 42586, and also keeps support for all other devices (CP2101/2/3). This patchfile is also attached to the bug report on bugzilla.kernel.org. This patch has been developed and test on the 3.2.0 mainline kernel version under Ubuntu 10.11. Signed-off-by:

Fix regression introduced by commit b1ffb4c8 ("USB: Fix Corruption issue in USB ftdi driver ftdi_sio.c") which caused the termios settings to no longer be initialised at open. Consequently it was no longer possible to set the port to the default speed of 9600 baud without first changing to another baud rate and back again. Reported-by:

Let's better properly stop gadget on shutdown too. This patch moves musb_gadget_cleanup out of musb_free(), which has 2 callsites: probe error path and musb_remove. On probe error path it was superflous since musb_gadget_cleanup is called explicitly there, and musb_remove() calls musb_shutdown(), so cleanup will get called as before. Signed-off-by:

Currently the UASP gadget fails to bind on an UDC which does not provide stream support. This is true for all udc in tree except for dummy and dwc3 since they don't support SuperSpeed. There is no need to test for the availability of stream support on those UDCs because we will never even try to use them. I think it is sane to assume that StreamSupport is always available on SuperSpeed since it is one of the key features. The host side will only allocate on SS so this part is also fine. Signed-off-by:
