Jonathan writes: 3rd set of IIO fixes for the 4.0 cycle. * A double free occured on an error path in due to an event registration issue. The fix is the minimal change rather than possibly reworking this area of the core to give a more elegant solution (future work). * A number of drivers were directly accessing indio_dev->buffer->scan_mask to identify the currently enabled channel set. This may not be correct if we have additional clients on the push interface. The correct option is indio_dev->active_scan_mask. This is fixed. * bmc150 had incorrectly specified sampling frequency (a datasheet confusion as they are specified in terms of bandwith - e.g. half the sampling frequency). * hmc5843 wasn't setting it's name and hence the name attribute was returning an empty string. * inv_mpu6050 wasn't clearing the locally held timestamp buffer when the hardware fifo was reset. Also an inconsistency existed in the interface for the scale of the channels. Magic numbers were written but real ones were used for the reads. Now uses real numbers (i.e. not array indexes) for both. * fix a missing dependency in the dummy driver. Previously shielded from the autobuilders by an earlier build error.

staging: iio: dummy: Fix undefined symbol build error

2015-03-14T18:36:20Z

CONFIG_SIMPLE_DUMMY_BUFFER compiles in iio_simple_dummy_buffer.c file which uses functions from industrialio-trigger.c. So, CONFIG_SIMPLE_DUMMY_BUFFER needs to select IIO_TRIGGER in order to avoid build error like this: > ERROR: "iio_trigger_notify_done" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_triggered_buffer_postenable" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_triggered_buffer_predisable" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_alloc_pollfunc" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_dealloc_pollfunc" [drivers/staging/iio/iio_dummy.ko] undefined!

vt6655: Fix late setting of byRFType.

2015-03-09T10:33:13Z

byRFType is not set prior to registration of mac80211 causing unpredictable operation after channel scans. With byRFType unset all channels are enabled this causes tx power to be set to values not present its eeprom. Move setting of this variable to vt6655_probe. byRFType must have a mask set. byRevId not used by driver and is removed.

staging: vt6655: vnt_tx_packet fix dma_idx selection.

2015-03-09T07:12:40Z

There is still a problem that dma_idx is causing packets to go onto the wrong tx path. Protect dma_idx fully with the present first lock and use pTDInfo->byFlags TD_FLAGS_NETIF_SKB to set MACvTransmit. Signed-off-by: Malcolm Priestley Signed-off-by: Greg Kroah-Hartman

staging: comedi: adv_pci1710: fix AI INSN_READ for non-zero channel

2015-03-02T03:25:59Z

Reading of analog input channels by the `INSN_READ` comedi instruction is broken for all except channel 0. `pci171x_ai_insn_read()` calls `pci171x_ai_read_sample()` with the wrong value for the third parameter. It is supposed to be the current index in a channel list (which is always of length 1 in this case, so the index should be 0), but instead it is passing the actual channel number. `pci171x_ai_read_sample()` checks the channel number encoded in the raw sample value read from the hardware matches the channel number stored in the specified index of the previously set up channel list and returns `-ENODATA` if it doesn't match. Since the index should always be 0 in this case, the match will fail unless the channel number is also 0. Fix it by passing 0 as the channel index. Note that when the bug first appeared, it was `pci171x_ai_dropout()` that was called with the wrong parameter value. `pci171x_ai_dropout()` got replaced with `pci171x_ai_read_sample()` in commit 7fd2dae2500d ("staging: comedi: adv_pci1710: introduce pci171x_ai_read_sample()").

staging: comedi: vmk80xx: remove "firmware version" kernel messages

2015-02-28T15:21:24Z

During the attach of this driver a couple commands are sent to the hardware with usb_bulk_msg() to read the firmware version information. This information is then dumped as dev_info() kernel messages. Thee messages are just added noise and don't effect the operation of the driver. For simplicity, remove the messages as well as the then unused functions vmk80xx_read_eeprom() and vmk80xx_check_data_link(). This also fixes an issue reported by coverity about an out-of-bounds write in vmk80xx_read_eeprom().

staging: comedi: comedi_isadma: fix "stalled" detect in comedi_isadma_disable_on_sample()

2015-02-28T15:20:37Z

The "stalled" variable this function is used to detect if the DMA operation is stalled while trying to disable DMA on a full comedi sample. The reset of this variable should only occur when the remaining bytes of the DMA transfer does not equal the remaining bytes from the last check.
