2013-01-07Merge branch 'staging-linus' into staging-nextGreg Kroah-Hartman
This is to get the comedi fixes, and resolve the issue in comdi_test.c and comedi_fops.c that were caused by changes in both branches. It also allows the fwserial driver changes to be applied, as they required the fixes that are in staging-linus. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-07staging: tidspbridge: use prepare/unprepare on dsp clocksOmar Ramirez Luna
This solves runtime failures while trying to enable WDT3 related functionality on firmware load, however it does affect other clocks controlled by the driver. Seen on 3.8-rc1. CCF provides clk_prepare and clk_unprepare for enable and disable operations respectively, this needs to be called in the correct order while handling clocks. Code path to enable/disable dsp clocks can still be reached from an atomic context, hence we can't use clk_prepare_enable and clk_disable_unprepare yet.

2013-01-07staging: comedi: comedi_test: fix race when cancelling commandIan Abbott
Éric Piel reported a kernel oops in the "comedi_test" module. It was a NULL pointer dereference within `waveform_ai_interrupt()` (actually a timer function) that sometimes occurred when a running asynchronous command is cancelled (either by the `COMEDI_CANCEL` ioctl or by closing the device file). This seems to be a race between the caller of `waveform_ai_cancel()` which on return from that function goes and tears down the running command, and the timer function which uses the command. In particular, `async->cmd.chanlist` gets freed (and the pointer set to NULL) by `do_become_nonbusy()` in "comedi_fops.c" but a previously scheduled `waveform_ai_interrupt()` timer function will dereference that pointer regardless, leading to the oops. Fix it by replacing the `del_timer()` call in `waveform_ai_cancel()` with `del_timer_sync()`.

The 'ni_at_a2150' module links to `cfc_write_to_buffer` in the 'comedi_fc' module, so selecting 'COMEDI_NI_AT_A2150' in the kernel config needs to also select 'COMEDI_FC'.

Represent the fake samples as unsigned shorts instead of signed shorts, as this is the usual Comedi convention.

2013-01-07staging: comedi: comedi_test: change end-of-acquisition testIan Abbott
In the "comedi_test" module's acquisition timer function `waveform_ai_interrupt()`, move the code for ending the acquisition outside the scan loop. Determine if the number of scans to be done is sufficient to end the acquisition before entering the scan loop. On leaving the scan loop, set the `COMEDI_CB_EOA` event if the acquisition is ending. Only reschedule the timer if the acquisition is not ending. Remove the somewhat useless `timer_running` flag from the private data. This was intended to stop the timer function adding the timer back on the timer queue periodically, but the flag setting wasn't synchronized with the timer and we already use `del_timer_sync()` to synchronize removal from the queue.

2013-01-07staging: comedi: store the 'index' for each subdeviceH Hartley Sweeten
Store the 'index' for each comedi_subdevice when they are initially allocated by comedi_alloc_subdevice(). This allows removing the pointer math in comedi_fops.c which is used to figure out the index that user space uses to access the individual subdevices. Fix the ni_mio_common driver so it also uses the 'index' instead of doing the pointer math. Also, remove a couple unused macros in the pcmda12, pcmmio, and pcmuio drivers which also do the pointer math to figure out the index.
