staging: comedi: cb_pcidas64: fix request_irq() warn
[ Upstream commit d2d106fe3badfc3bf0dd3899d1c3f210c7203eab ]
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()
