Subject: staging: comedi: dnya_pci10xx: remove thisboard and devpriv macros
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=af0677c14e990e64bd6571be691e0bebd82a5dc0;p=linux-beck.git

staging: comedi: dnya_pci10xx: remove thisboard and devpriv macros

These macros rely on local variables having a specific name. Replace
them with local variables where used. Use the comedi_board() helper
to get the thisboard pointer.
