staging: comedi: cb_pcidas: fix request_irq() warn
[ Upstream commit 2e5848a3d86f03024ae096478bdb892ab3d79131 ]
request_irq() wont accept a name which contains slash so we need to
repalce it with something else -- otherwise it will trigger a warning
and the entry in /proc/irq/ will not be created
since the .name might be used by userspace and we don't want to break
userspace, so we are changing the parameters passed to request_irq()
