From: H Hartley Sweeten Date: Sat, 18 Aug 2012 01:20:34 +0000 (-0700) Subject: staging: comedi: adv_pci_dio: add the number of subdevices to the boardinfo X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4bf75257ff84a57d2e878f149514e4fcd23a93bd;p=linux-beck.git staging: comedi: adv_pci_dio: add the number of subdevices to the boardinfo Instead of calculating the number of subdevices in the 'attach' simply add the number to the boardinfo.
