[PATCH v2 2/4] ntb_hw_intel: Style fixes: open code macros that just obfuscate code
From: Logan Gunthorpe
Date: Tue Jan 10 2017 - 19:33:56 EST
As per a comments in [1] by Greg Kroah-Hartman, the ndev_* macros should
be cleaned up. This makes it more clear what's actually going on when
reading the code.
