X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7e94e51525d3a289ed0c60b57dff36630a8413e4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mfd: sm501: Constify gpio_chip structures

These structures are only used to copy into other structures, so declare
them as const.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct gpio_chip i@p = { ... };

@ok@
identifier r.i;
expression e;
position p;
@@
e = i@p;

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct gpio_chip e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;

static
+const
 struct gpio_chip i = { ... };
// </smpl>
