staging: unisys: Allow visorbus to autoload

2015-09-21T17:10:46+00:00

commit 1fc07f99134ba0b8d4099322ea0753137ea7ed3b upstream.

We inadvertently remove the MODULE_DEVICE_TABLE line for visorbus,
this patch adds it back in.

staging: comedi: usbduxsigma: don't clobber ao_timer in command test

2015-09-21T17:10:46+00:00

commit c04a1f17803e0d3eeada586ca34a6b436959bc20 upstream.

`devpriv->ao_timer` is used while an asynchronous command is running on
the AO subdevice.  It also gets modified by the subdevice's `cmdtest`
handler for checking new asynchronous commands,
`usbduxsigma_ao_cmdtest()`, which is not correct as it's allowed to
check new commands while an old command is still running.  Fix it by
moving the code which sets up `devpriv->ao_timer` into the subdevice's
`cmd` handler, `usbduxsigma_ao_cmd()`.

Note that the removed code in `usbduxsigma_ao_cmdtest()` checked that
`devpriv->ao_timer` did not end up less that 1, but that could not
happen due because `cmd->scan_begin_arg` or `cmd->convert_arg` had
already been range-checked.

Also note that we tested the `high_speed` variable in the old code, but
that is currently always 0 and means that we always use "scan" timing
(`cmd->scan_begin_src == TRIG_TIMER` and `cmd->convert_src == TRIG_NOW`)
and never "convert" (individual sample) timing (`cmd->scan_begin_src ==
TRIG_FOLLOW` and `cmd->convert_src == TRIG_TIMER`).  The moved code
tests `cmd->convert_src` instead to decide whether "scan" or "convert"
timing is being used, although currently only "scan" timing is
supported.

staging: comedi: usbduxsigma: don't clobber ai_timer in command test

2015-09-21T17:10:45+00:00

commit 423b24c37dd5794a674c74b0ed56392003a69891 upstream.

`devpriv->ai_timer` is used while an asynchronous command is running on
the AI subdevice.  It also gets modified by the subdevice's `cmdtest`
handler for checking new asynchronous commands
(`usbduxsigma_ai_cmdtest()`), which is not correct as it's allowed to
check new commands while an old command is still running.  Fix it by
moving the code which sets up `devpriv->ai_timer` and
`devpriv->ai_interval` into the subdevice's `cmd` handler,
`usbduxsigma_ai_cmd()`.

Note that the removed code in `usbduxsigma_ai_cmdtest()` checked that
`devpriv->ai_timer` did not end up less than than 1, but that could not
happen because `cmd->scan_begin_arg` had already been checked to be at
least the minimum required value (at least when `cmd->scan_begin_src ==
TRIG_TIMER`, which had also been checked to be the case).

staging: comedi: adl_pci7x3x: fix digital output on PCI-7230

2015-09-21T17:10:45+00:00

commit ad83dbd974feb2e2a8cc071a1d28782bd4d2c70e upstream.

The "adl_pci7x3x" driver replaced the "adl_pci7230" and "adl_pci7432"
drivers in commits 8f567c373c4b ("staging: comedi: new adl_pci7x3x
driver") and 657f77d173d3 ("staging: comedi: remove adl_pci7230 and
adl_pci7432 drivers").  Although the new driver code agrees with the
user manuals for the respective boards, digital outputs stopped working
on the PCI-7230.  This has 16 digital output channels and the previous
adl_pci7230 driver shifted the 16 bit output state left by 16 bits
before writing to the hardware register.  The new adl_pci7x3x driver
doesn't do that.  Fix it in `adl_pci7x3x_do_insn_bits()` by checking
for the special case of the subdevice having only 16 channels and
duplicating the 16 bit output state into both halves of the 32-bit
register.  That should work both for what the board actually does and
for what the user manual says it should do.

This patch fixes issue generated by commit ca93dcba3a92
("staging: rtl8192e: Remove assert() macro")

One negation was missed in conversion, therefore
asserted message was always printed.

Include unaligned.h instead and leave it up to the architecture to decide
how to implement unaligned accesses.

conf->beacon_rate can be NULL on association. So check conf->beacon_rate

BSS_CHANGED_BEACON_INFO needs to flagged in changed as the beacon_rate
