2013-06-26ARM: at91/DT: fix SPI compatibility stringNicolas Ferre
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". Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Tested-by: Wenyou Yang <wenyou.yang@atmel.com>

2013-05-09ARM: OMAP2+: Remove bogus IS_ERR_OR_NULL checking from id.cTony Lindgren
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.
