7f8750ada0 pinctrl: freescale: remove needless module.h include 
None of these files have anything modular in them, so they
don't need to be bringing in module.h and all its dependencies.

56411f3c05 pinctrl: fix incorrect inline keyword in multiple drivers 
When building with 'make W=1', we get harmless warnings about
five drivers in drivers/pinctrl, which all contain a copy of
the same line:

drivers/pinctrl/freescale/pinctrl-imx1-core.c:160:1: error: 'inline' is not at beginning of declaration [-Werror=old-style-declaration]

This replaces the somewhat nonstandard 'static const inline'
with 'static inline const', which has the same meaning but
does not cause this warning.

0563df2ce7 pinctrl: imx1-core: add missing of_node_put 
for_each_child_of_node performs an of_node_get on each iteration,
so of_node_put is required on break out of the loop.

This is done using Coccinelle. And semantic patch used for this is
as follows:

@@
expression root,e;
local idexpression child;
@@

 for_each_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
(
   return child;
|
+  of_node_put(child);
?  return ...;
)
   ...
 }

9571b25df1 Subject: pinctrl: imx1-core: Fix debug output in .pin_config_set callback 
imx1_pinconf_set assumes that the array of pins in struct
imx1_pinctrl_soc_info can be indexed by pin id to get the
pinctrl_pin_desc for a pin. This used to be correct up to commit
607af165c0 which removed some entries from the array and so made it
wrong to access the array by pin id.

The result of this bug is a wrong pin name in the output for small pin
ids and an oops for the bigger ones.

This patch is the result of a discussion that includes patches by Markus
Pargmann and Chris Ruehl.

323de9efdf pinctrl: make pinctrl_register() return proper error code 
Currently, pinctrl_register() just returns NULL on error, so the
callers can not know the exact reason of the failure.

Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some
-ENOMEM on error of pinctrl_register(), although the error code
might be different from the real cause of the error.

This commit reworks pinctrl_register() to return the appropriate
error code and modifies all of the pinctrl drivers to use IS_ERR()
for the error checking and PTR_ERR() for getting the error code.

its own subdirectory to clear the view.
