From: H Hartley Sweeten Date: Wed, 18 Nov 2015 17:07:25 +0000 (-0700) Subject: staging: comedi: adv_pci_dio: cleanup PCI-1753 interrupt register defines X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=774a8c57b14646c74c439097e1e6d06b50c21b85;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: comedi: adv_pci_dio: cleanup PCI-1753 interrupt register defines For aesthetics, replace these defines with some macros. Refactor the switch in pci_dio_reset() to not require the fallthrough comment.
