2014-11-26staging: comedi: dmm32at: introduce dmm32_ai_get_sample()H Hartley Sweeten1-24/+16
Introduce a helper function to read the two's complement analog input sample from the hardware and munge it to the offset binary (unsigned) format that comedi expects. Use the comedi_offset_munge() helper to munge the data. Use the new helper in the analog input (*insn_read) and in the interrupt handler for the async command.

2014-11-26staging: comedi: dmm32at: make AI (*cancel) actually cancel async commandH Hartley Sweeten1-5/+2
Currently the AI (*cancel) changes a private data member to cause the interrupt handler to cancel the async command after the next interrupt. Move the code that disables the interrupt and terminates the acquisition from the interrunt handler into dmm32at_ai_cancel() so that the async command is terminated instantly.

2014-11-26staging: comedi: adl_pci9111: use comedi_async 'scans_done' to detect EOAH Hartley Sweeten1-24/+4
The comedi core now counts the number of samples added to the async buffer and detects the end-of-scan and increments the comedi_async 'scans_done' counter. Remove the private data member 'stop_counter' and use the 'scans_done' member to detect the end-of-acquisition. This fixes a possible interger overflow when calculating the value of the 'stop_counter' and removes the need to accumulate the 'total' number of samples added to the async buffer in pci9111_handle_fifo_half_full().

The timer subdevice is currently broken in this driver. The Rev 1.0 and 2.x versions of the board both have a 12-bit timer. But only the Rev 2.x boards have the 3 32-bit counters. Split the current timer subdevice into two separate subdevices: 1) A single channel 12-bit timer subdevice 2) A three channel 32-bit counter subdevice This represents the hardware correctly and the counters can be disabled on the Rev 1.0 boards.

The current version check "if (hmi_evt->version != OpalHMIEvt_V1)" doesn't accomodate the fact that the version number may change in future.

2014-11-26staging: android: ion: Deletion of unnecessary checks before two function callsMarkus Elfring3-12/+6
The functions ion_heap_destroy() and vfree() perform also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== pull request: wireless 2014-11-26 Please pull this little batch of fixes intended for the 3.18 stream... For the iwlwifi one, Emmanuel says: "Not all the firmware know how to handle the HOT_SPOT_CMD. Make sure that the firmware will know this command before sending it. This avoids a firmware crash." Along with that, Larry sends a pair of rtlwifi fixes to address some discrepancies from moving drivers out of staging. Larry says: "These two patches are needed to fix a regression introduced when driver rtl8821ae was moved from staging to the regular wireless tree." Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <[email protected]>
