The previous implementation flawed, in case some channels are not enabled.
The sorted array would then include channel information of disabled channels,
And misses the enabled ones, when the count is reached.
More troublesome, the loop would not even terminate.
The fix is twofold:
First we skip channels that are not enabled.
Then we use a tested bubble sort algorithm to sort the array.
Since we already allocated exactly the number of bytes we need.
We can exercise bubble sort on the original memory.
In all cases I've seen, the array is already sorted, so this sort
terminates immediately.

The first part of build_channel_array()identifies the number of enabled channels.
Further down this count is used to allocate the ci_array. The next section parses the
scan_elements directory again, and fills ci_array regardless if the channel is enabled or not.
So if less than available channels are enabled ci_array memory is overflowed.
This fix makes sure that we allocate enough memory. But the whole approach looks a bit
cumbersome to me. Why not allocate memory for MAX_CHANNLES, less say 64
(I never seen a part with more than that channels). And skip the first part entirely.

This is a complete rewrite of the AD9832/35 driver.
Purpose was to move this driver to the recently
created API for such devices.
Changes since V1:
IIO: DDS: AD9832 / AD9835 driver: Apply review feedback
Save a few bytes, use union for data allocated for spi buffers.
Remove use of device IDs.
Fix comments.
Make master clock mclk always type unsigned long.

This patch adds a new trigger that can be invoked by writing
the sysfs file: trigger_now. This approach can be valuable during
automated testing or in situations, where other trigger methods
are not applicable. For example no RTC or spare GPIOs.
Last but not least we can allow user space applications to produce triggers.
IIO: TRIGGER: Apply review feedback by Greg Kroah-Hartman

Add sysfs documentation.
Change license notice.

This is a static checker patch and I don't have this hardware.
This code is unusual because while I've often seen a double lock, this
is the first time I've seen code that takes a lock 11 times in a row. I
feel like I must have missed something. But I've looked very carefully
I don't see any way the original code is correct. Does spi_sync()
somehow release the lock in a way that I can't see? Even if it does,
the locking would still be wrong.
