From: Adrian Bunk Date: Wed, 16 Jul 2008 23:08:12 +0000 (+0300) Subject: kbuild: scripts/genksyms/lex.l: add %option noinput X-Git-Tag: v2.6.27-rc2~98^2~4 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=11ddad396086f8d1dfcb0056dc9d65d228f755c1;p=linux-2.6 kbuild: scripts/genksyms/lex.l: add %option noinput gcc 4.3 correctly determines that input() is unused and gives the following warning: <-- snip --> ... HOSTCC scripts/genksyms/lex.o scripts/genksyms/lex.c:1487: warning: ‘input’ defined but not used ... <-- snip --> Fix it by adding %option noinput to scripts/genksyms/lex.l and regeneration of scripts/genksyms/lex.c_shipped.
