mfd: sm501: Constify gpio_chip structures

2016-10-04T14:48:03+00:00

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/)

// 
@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;
@@

+const
 struct gpio_chip i = { ... };

mfd: sm501: Use gpiochip data pointer

2016-04-19T06:58:37+00:00

This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

mfd: sm501: Fix module autoload for OF platform driver

2015-10-26T14:49:02+00:00

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

mfd: drop owner assignment from platform_drivers

2014-10-20T14:20:53+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

mfd: sm501: Avoid implicit sign extension

2014-09-26T07:15:34+00:00

Suspicious implicit sign extension where 'reg' (unsigned char) is
promoted in reg << clksrc to int, then sign-extended to unsigned
long. If reg << clksrc is greater than 0x7FFFFFFF, the upper bits
of the result will all be 1.

mfd: sm501: Remove unnecessary pci_set_drvdata()

2013-10-23T15:20:54+00:00

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
