We dereference "param->u.wpa_key.key" on the next line so the check here is inconsistent. This is only called from iwctl_siwencodeext() and "param->u.wpa_key.key" is a valid pointer.

2014-01-08xhci: Set scatter-gather limit to avoid failed block writes.Sarah Sharp
Commit 35773dac5f862cb1c82ea151eba3e2f6de51ec3e "usb: xhci: Link TRB must not occur within a USB payload burst" attempted to fix an issue found with USB ethernet adapters, and inadvertently broke USB storage devices. The patch attempts to ensure that transfers never span a segment, and rejects transfers that have more than 63 entries (or possibly less, if some entries cross 64KB boundaries). usb-storage limits the maximum transfer size to 120K, and we had assumed the block layer would pass a scatter-gather list of 4K entries, resulting in no more than 31 sglist entries: http://marc.info/?l=linux-usb&m=138498190419312&w=2 That assumption was wrong, since we've seen the driver reject a write that was 218 sectors long (of probably 512 bytes each): Jan 1 07:04:49 jidanni5 kernel: [ 559.624704] xhci_hcd 0000:00:14.0: Too many fragments 79, max 63 ...

That should be margin enough in case some entries cross 64KB boundaries. Increase the number of TRBs per segment from 64 to 256, which should result in ring segments fitting on a 4K page.

2014-01-08xhci: Avoid infinite loop when sg urb requires too many trbsBen Hutchings
Currently prepare_ring() returns -ENOMEM if the urb won't fit into a single ring segment. usb_sg_wait() treats this error as a temporary condition and will keep retrying until something else goes wrong. The number of retries should be limited in usb_sg_wait(), but also prepare_ring() should not return an error code that suggests it might be worth retrying. Change it to -EINVAL.

This patch defines the appropriate register values for different oparation modes and IP versions. We have to handle DMA/FIQ, AC97, DEBUG-IRQs and offline/online configuration support. With this patch we cleanup some driver code that was not reference manual conform and try to cleanup the whole trigger function to seperate the actual register values from the enable/disable logic, which is now hidden in fsl_ssi_config helpers.

2014-01-08ASoC: fsl-ssi: Add configuration helper functionsMarkus Pargmann
This patch adds a struct 'fsl_ssi_rxtx_reg_val' which holds register values necessary to enable rx/tx. Based on those preset register values, the added configuration functions will cleanly enable/disable different parts of the SSI IP while supporting online/offline configuration. Different operating modes can be setup directly as different register values in fsl_ssi_reg_val. These functions and structs will help to cleanup and simplify the trigger function to support many different IP versions (online/offline configuration) and different operating modes.

2014-01-08ASoC: fsl-ssi: Add imx51-ssi and of_device_id matchingMarkus Pargmann
There is a small but significant difference between imx21-ssi and imx51-ssi and above. imx21-ssi does not allow online reconfiguration of some registers. They have to be configured at the beginning. imx51-ssi has to reconfigure the SSI unit while it is running. Otherwise it would not be possible to have two streams in parallel. The new SDMA unit in imx51 and above has to be configured before the first DMA request arrives. Therefor we need to setup TDMAE/RDMAE just before starting the stream. This patch introduces distinct imx51-ssi as compatible and adds of_device_id matching in the probe function.

2014-01-08clk: clk-divider: fix divisor > 255 bugJames Hogan
Commit 6d9252bd9a4bb (clk: Add support for power of two type dividers) merged in v3.6 added the _get_val function to convert a divisor value to a register field value depending on the flags. However it used the type u8 for the div field, causing divisors larger than 255 to be masked and the resultant clock rate to be too high. E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This was masked to 238 (0xee) resulting in a frequency of 103.26KHz.

Both patch_realtek.c and patch_conexant.c contain the fairy same code snippet for supporting Thinkpad ACPI LED controls. Split them into thinkpad_helper.c and include it from both places. Although this isn't the best approach from the code size POV, the probability for coexistence of both Realtek and Conexant codecs on a single machine is pretty low, thus it'll end up with less memory footprint than splitting to yet another module.

2014-01-08gpio / ACPI: register to ACPI events automaticallyMika Westerberg
Instead of asking each driver to register to ACPI events we can just call acpi_gpiochip_register_interrupts() for each chip that has an ACPI handle. The function checks chip->to_irq and if it is set to NULL (a GPIO driver that doesn't do interrupts) the function does nothing. We also add the a new header drivers/gpio/gpiolib.h that is used for functions internal to gpiolib and add ACPI GPIO chip registering functions to that header.

2014-01-08GFS2: Add hints to directory leaf blocksSteven Whitehouse
This patch adds four new fields to directory leaf blocks. The intent is not to use them in the kernel itself, although perhaps we may be able to use them as hints at some later date, but instead to provide more information for debug/fsck use. One new field adds a pointer to the inode to which the leaf belongs. This can be useful if the pointer to the leaf block has become corrupt, as it will allow us to know which inode this block should be associated with. This field is set when the leaf is created and never changed over its lifetime. The second field is a "distance from the hash table" field. The meaning is as follows: 0 = An old leaf in which this value has not been set 1 = This leaf is pointed to directly from the hash table 2+ = This leaf is part of a chain, pointed to by another leaf block, the value gives the position in the chain. The third and fourth fields combine to give a time stamp of the most recent directory insertion or deletion from this leaf block. The time stamp is not updated when a new leaf block is chained from the current one. The code is currently written such that the timestamp on the dir inode will match that of the leaf block for the most recent insertion/deletion. For backwards compatibility, any of these new fields which is zero should be considered to be "unknown". Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
