soc: integrator: Drop pointless static qualifier in integrator_soc_init()

2020-08-20T06:57:05+00:00

There is no need to have the 'struct regmap *syscon_regmap' variable
static since new value always be assigned before use it.

soc: integrator: Use custom soc attribute group instead of device_create_file

2020-07-06T08:48:05+00:00

Commit c31e73121f4c ("base: soc: Handle custom soc information sysfs
entries") introduced custom soc attribute group in soc_device_attribute
structure but there are no users treewide. While trying to understand
the motivation and tried to use it, it was found lot of existing custom
attributes can moved to use it instead of device_create_file.

Though most of these never remove/cleanup the custom attribute as they
never call soc_device_unregister, using these custom attribute group
eliminate the need for any cleanup as the driver infrastructure will
take care of that.

Let us remove device_create_file and start using the custom attribute
group in soc_device_attribute.

soc: integrator: Switch to use DEVICE_ATTR_RO()

2020-07-06T08:48:05+00:00

Move device attributes to DEVICE_ATTR_RO() as that would make things
a lot more "obvious" what is happening over the existing __ATTR usage.

soc: versatile: remove unnecessary static in realview_soc_probe()

2017-08-16T20:28:27+00:00

Remove unnecessary static on local variables syscon_regmap.
Such variables are initialized before being used, on every
execution path throughout the functions. The static has no
benefit and, removing it reduces the object file size.

This issue was detected using Coccinelle and the following
semantic patch:

@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;

In the following log you can see the difference in the object file size.
This log is the output of the size command, before and after the code
change:

before:
   text    data     bss     dec     hex filename
   3339    2104     128    5571    15c3 drivers/soc/versatile/soc-realview.o

after:

   3321    2048      64    5433    1539 drivers/soc/versatile/soc-realview.o
