From 2b51dca79a105dea022776ea7874193239df7fbd Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Mon, 8 Nov 2010 14:44:34 +0100 Subject: [PATCH] floppy: replace NO_GEOM macro with a function This patch replaces the NO_GEOM macro with a proper static inline function and converts an open-coded caller in check_floppy_change() to use it.
