USB: regroup all depends on USB within an if USB block

2013-04-09T23:49:07+00:00

This patch removes the depends on USB from all config symbols in
drivers/usb/host/Kconfig and replace that with an if USB / endif block
as suggested by Alan Stern. Some source ... Kconfig lines have been
shuffled around to permit a better regroupment of the Kconfig files
depending on "config USB" item. No functionnal change is introduced.

USB: wusbcore/wa-xfer: error handling fixes in setup_segs()

2013-02-06T19:38:14+00:00

1) It didn't free xfer->seg[0] so there was a leak.
2) xfer->seg[cnt] can be NULL.
3) Use usb_free_urb() for ->dto_urb instead of kfree().

WUSB: remove an unnused variable

2012-10-22T18:33:34+00:00

The "wusb_cap_descr_default" is never used.  GCC doesn't complain about
it because we have that line ".bLength = sizeof(wusb_cap_descr_default)"
inside the definition itself.  Clang complains though.

USB: remove CONFIG_EXPERIMENTAL dependancies

2012-09-18T06:00:15+00:00

As discussed at the kernel summit this year, CONFIG_EXPERIMENTAL means
nothing, so let's get rid of it.

drivers/usb/wusbcore/wa-hc.c: fix error return code

2012-08-15T22:17:40+00:00

Convert a 0 error return code to a negative one, as returned elsewhere in the
function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@@
identifier ret;
expression e,e1,e2,e3,e4,x;
@@

(
if (\(ret != 0\|ret < 0\) || ...) { ... return ...; }
|
ret = 0
)
... when != ret = e1
*x = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\|ioremap\|ioremap_nocache\|devm_ioremap\|devm_ioremap_nocache\)(...);
... when != x = e2
    when != ret = e3
*if (x == NULL || ...)
{
  ... when != ret = e4
*  return ret;
}

USB: wusb: Use kcalloc instead of kzalloc to allocate array

2011-12-10T00:18:20+00:00

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.
