Subject: staging: comedi: 8255: remove have_irg and refactor subdev_8255_init_irq
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=34cfcf9acc6b0697e71294007c57eae91b80005c;p=linux-beck.git

staging: comedi: 8255: remove have_irg and refactor subdev_8255_init_irq

The have_irq variable in the 8255 private data is not used by the driver,
remove it.  This removes the need to access the private data in the
subdev_8255_init_irq function.

Also, add a bit of whitespace to improve the readability.
