Introduce a new member to comedi_async to count the number of scans completed. This member is cleared by comedi_buf_reset() along with the other comedi_async members. It is incremented in comedi_inc_scan_progress() when the end of scan is detected. This member will be used to clean up the scan counting in the comedi drivers.

Wake queue in the dwIsr loop of device_intr instead of device_tx_srv. This fixes an issue when ISR_TXDMA0 or ISR_AC0DMA does not occur device_tx_srv is not called and the queue gets stuck in stopped condition. On test if the queue is stuck another MACvTransmitAC0 or MACvTransmit0 in vnt_tx_packet will clear it. Check on vif that both buffers are available and the queue is stopped.

Now that Comedi has the structures in place to support setting the current "read" and/or "write" subdevice on a per-file object basis, add new ioctls to set them. The newly chosen "read" ("write") subdevice needs to support "read" ("write") commands, and the file cannot be busy handling a "read" ("write") command on the previous subdevice (if any).

Comedi devices may have several subdevices that support "read" and/or "write" asynchronous commands that use the "read" or "write" file operations for data transfer. The low-level Comedi drivers may nominate a default "read" subdevice and/or a default "write" subdevice, but it may have other subdevices that support asynchronous commands. The Comedi core provides a somewhat clunky mechanism to provide access to the asynchronous command support of the non-default subdevices. When a low-level device is "attached" to a core Comedi device, it dynamically allocates a minor device number for each of the subdevices that support asynchrounous commands and associates them with files created in SysFS named "comediX_subdY", where "X" is the minor device number of the main comedi device, and "Y" is the subdevice number. An application can open these subdevice-specific files and they behave like the regular "comediX" files except that the "read" and/or "write" subdevice may be different to the default chosen by the low-level driver. This patch adds a layer of indirection between the file object and the comedi device object to allow the current "read" and/or "write" subdevice to be altered after opening the Comedi device, on a per-file object basis. The advantage is that an application only needs to open the main Comedi device file and can then choose which subdevice it wants to "read" or "write". The main Comedi device file can be opened more than once, and each file object can choose the "read" and "write" subdevices independently. The new `struct comedi_file` is created on "open" and freed on "release". It includes pointers to the main Comedi device structure, and to the current "read" and "write" subdevice structures (which may be NULL). It also has information to keep track of when a low-level device has been attached or detached since the previous time the file object was used. In that case, the current "read" and "write" subdevices in the `struct comedi_file` will be changed to the new defaults (or set to NULL). (The change to new defaults is done by `comedi_file_reset()`. The checking for attach/detach is done by `comedi_file_check()` which will call `comedi_file_reset()` if there have been any attach/detach operations since the previous call.) A subsequent patch will add the ioctls to change the current "read" and "write" subdevices.

According to the datasheet and as defined in struct bmp280_comp_press, dig_p1 is of type u16, while dig_p2 to dig_p9 are of type s16. In bmp280_read_compensation_press(), values read from the device were treated as the wrong type. In bmp280_read_press() the fractional part of the measured pressure is calculated wrong. A better way is to use *val for the raw pressure and *val2 for the quotient and let the core do the proper conversion using IIO_VAL_FRACTIONAL.

The ADC on exynos7 is quite similar to ADCv2. The differences are as follows: - exynos7-adc has 8 input channels (as against 10 in ADCv2). - exynos7 does not include an ADC PHY control register. - Some ADC_CON2 register bits being used in ADCv2 are listed as reserved in exynos7-adc. This results in a different init_hw function for exynos7.
