Subject: [PATCH v2 52/72] ncr5380: Remove H_NO macro and introduce dsprintk
Date: Sun, 06 Dec 2015 12:32:18 +1100 [thread overview]
Message-ID: <20151206013139.876611367@telegraphics.com.au> (raw)
In-Reply-To: 20151206013126.995379403@telegraphics.com.au
[-- Attachment #1: atari_NCR5380-remove-H_NO-and-introduce-dsprintk --]
[-- Type: text/plain, Size: 8848 bytes --]
Replace all H_NO and some HOSTNO macros (both peculiar to atari_NCR5380.c)
with a new dsprintk macro that's more useful and more consistent. The new
macro avoids a lot of boilerplate in new code in subsequent patches. Keep
NCR5380.c in sync. Remaining HOSTNO macros are removed as side-effects
of subsequent patches.
