Remove typedef from struct as linux-kernel coding style tends to
avoid using typedefs
Done using following coccinelle semantic patch
@r1@
type T;

typedef struct { ... } T;
@script:python c1@
T2;
T << r1.T;
@@
if T[-2:] =="_t" or T[-2:] == "_T":
coccinelle.T2 = T[:-2];
else:
coccinelle.T2 = T;
print T, coccinelle.T2
@r2@
type r1.T;
identifier c1.T2;

-typedef
