Subject: usb: dwc3: keystone: fix error return code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=62c606978aa028260f88d0dcb9834bbb7a42b048;p=linux-beck.git

usb: dwc3: keystone: fix error return code

Return a negative error code on failure.

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

// <smpl>
@@
identifier ret; expression e1,e2;
@@
(
if (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>
