In previous version of SPI driver we where using different compatibility stings
for finding SPI features. We are now using the IP revision information.
So we stay with the unique compatibility string for this driver:
"atmel,at91rm9200-spi".

GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
possible to do so which has been causing confusion and breakage. This
branch does the work to completely eliminate GENERIC_GPIO.
However, it is not trivial to just create a branch to remove it. Over
the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
added to linux-next that conflicts with this branch. The following must
be done to resolve the conflicts when merging this branch into mainline:
* "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
replaced with CONFIG_GPIOLIB
* "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
documentation.
* Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
* definitions of the option in architecture Kconfig code should be deleted.
Stephen has 3 merge fixup patches[1] that do the above. They are currently
applicable on mainline as of May 2nd.

Commit 6770b211 (ARM: OMAP2+: Export SoC information to userspace)
had some broken return value handling as noted by Russell King:
+ soc_dev = soc_device_register(soc_dev_attr);
+ if (IS_ERR_OR_NULL(soc_dev)) {
+ kfree(soc_dev_attr);
+ return;
+ }
+
+ parent = soc_device_to_device(soc_dev);
+ if (!IS_ERR_OR_NULL(parent))
+ device_create_file(parent, &omap_soc_attr);
This is nonsense. For the first, IS_ERR() is sufficient. For the second,
tell me what error checking is required in the return value of this
function:
struct device *soc_device_to_device(struct soc_device *soc_dev)
{
return &soc_dev->dev;
}
when you've already determined that the passed soc_dev is a valid pointer.
If you read the comments against the prototype:
/**
* soc_device_to_device - helper function to fetch struct device
* @soc: Previously registered SoC device container
*/
struct device *soc_device_to_device(struct soc_device *soc);
if "soc" is valid, it means the "previously registered SoC device container"
must have succeeded and that can only happen if the struct device has been
registered. Ergo, there will always be a valid struct device pointer for
any registered SoC device container. Therefore, if soc_device_register()
succeeds, then the return value from soc_device_to_device() will always be
valid and no error checking of it is required.
Simples. The rule as ever applies here: get to know the APIs your using
and don't fumble around in the dark hoping that you'll get this stuff
right.
Fix it as noted by Russell.
