few comments to provide some clues to the reader.

feb153f326 staging: comedi: rtd520: cleanup the range tables
Change the whitespace of the range tables to avoid the > 80
character lines and the ugly line breaks. Convert a couple of
the RANGE() values into the appropriate {UNI,BIP}_RANGE().

26550b32e1 staging: comedi: rtd520: cleanup the "find pci device" code
Use for_each_pci_dev() instead of open-coding the for loop. Create
local variables for the bus and slot options as well as the thisboard
pointer in order to clarify the code. Consolidate the printk's when
a supported board is not found into one dev_warn message.

9e81c8761c staging: comedi: rtd520: remove thisboard macro
The macro 'thisboard' relies on a local variable having a specific
name and yeilds a pointer derived from that local variable. Replace
the macro with a local variable where used and use the comedi_board()
helper to get the pointer.

97271c3bcb staging:iio:adis16260: Fix drvdata inconsistency
The SPI drvdata is set to adis16260_state struct in probe(), but assumed to be
the iio_dev struct in remove(). Fix this by setting it to the iio_dev in
probe().

The issue has been discovered using the following coccinelle patch:

2b6e6b8042 staging: comedi: rtd520: remove RtdDio0Read macro
This macro uses the 'devpriv' macro which relies on a local variable
having a specific name. Plus it's just a wrapper around a simple
'readw'. Remove the macro.
