Subject: staging: comedi: daqboard2000: remove 'got_regions' from private data
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f55354b0a8a3c6d3e5fc64b3da37510711aaf352;p=linux-beck.git

staging: comedi: daqboard2000: remove 'got_regions' from private data

The 'got_regions' variable in the private data is used as a flag
for the detach to know if the pci device has been enabled.

Typically the dev->iobase variable is used to indicate this in
all the other comedi drivers. Do the same here for consistancy.
