Subject: Staging: comedi: add local copy of interrupt.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=74b847f4d07bce1eaf84505d65aff42f14e5fb2f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Staging: comedi: add local copy of interrupt.h

This is needed for some internal comedi driver macros that were
built up over the years to handle multiple kernel versions.  It will be
removed eventually.
