2013-08-19staging: vt6656: desc.h: Move typedef struct tagSRrvTime_gCTS to new ↵Malcolm Priestley
structure in rxtx.h To new structure. typedef struct tagSRrvTime_gCTS -> struct vnt_rrv_time_cts This is only needed by rxtc.c so moved to rxtx.h and will eventually form part of the structure of struct vnt_tx_buffer.

2013-08-19Merge tag 'iio-for-3.12b' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second round of new drivers, features and cleanups for IIO in the 3.12 cycle. New driver: 1) tmp006 IR thermopile driver. This is an unusual temperature sensor and was taken in to IIO with the knowledge and agreement of a hwmon maintainer. It measures remote temperature using infrared emissions. I guess taking this may mean we have to fight off submissions of devices much more suited to hwmon but such is life and we end up doing this from time to time already. 2) twl6030 adc driver. Cleanups: 1) More devm_* cleanups following on from the introduction of devm_iio_device_alloc. Mostly an heroic effort from Sachin Kamat! 2) Introduce devm_iio_trigger_alloc etc to handle trigger allocation and deallocation in a managed fashion. There aren't as many instances of triggers as devices, but this will allow futher reduction in error patch complexity in some of our most complex drivers making it a very good thing. 3) Trivial removal of unused defines in adjd_s311 4) Drop some write_raw_get_fmt callbacks where they were only returning the default value. 5) Change mxs-lradc realbits to 12. Whilst an 18bit register is used on the device, in its current mode only 12 bits of useful data are returned. For now the packing is unchanged in the buffer and this change mainly effects the input support in the driver.

2013-08-19pstore: Add compression support to pstoreAruna Balakrishnaiah
Add compression support to pstore which will help in capturing more data. Initially, pstore will make a call to kmsg_dump with a bigger buffer and will pass the size of bigger buffer to kmsg_dump and then compress the data to registered buffer of registered size. In case compression fails, pstore will capture the uncompressed data by making a call again to kmsg_dump with registered_buffer of registered size. Pstore will indicate the data is compressed or not with a flag in the write callback.

2013-08-19proc: return on proc_readdir errorRichard Genoud
Commit f0c3b5093add ("[readdir] convert procfs") introduced a bug on the listing of the proc file-system. The return value of proc_readdir() isn't tested anymore in the proc_root_readdir function. This lead to an "interesting" behaviour when we are using the getdents() system call with a buffer too small: instead of failing, it returns the first entries of /proc (enough to fill the given buffer), plus the PID directories. This is not triggered on glibc (as getdents is called with a 32KB buffer), but on uclibc, the buffer size is only 1KB, thus some proc entries are missing. See https://lkml.org/lkml/2013/8/12/288 for more background.
