[alsa-devel] [PATCH v2] ALSA: usb-audio: Change structure initialisation to C99 style

[Amitoj Kaur Chawla]

To allow for structure randomisation, replace the in order struct
initialisation style with explicit field style.

The Coccinelle semantic patch used to make this change is as follows:

@decl@
identifier i1,fld;
type T;
field list[n] fs;
@@

struct i1 {
 fs
 T fld;
 ...};

@@
identifier decl.i1,i2,decl.fld;
expression e;
position bad.p, bad.fix;
@@

struct i1 i2 at p = { ...,
+ .fld = e
- e at fix
 ,...};
