Subject: [PATCH] jffs2: fix if/else empty body warnings
Date: Sun, 5 Apr 2020 14:22:56 -0700 [thread overview]
Message-ID: <1f7332d5-c08d-77e2-e194-ce929eae7147@infradead.org> (raw)
From: Randy Dunlap <rdunlap@infradead.org>
When debug (print) macros are not enabled, change them to use the
no_printk() macro instead of <nothing>. This fixes gcc warnings when
-Wextra is used:
../fs/jffs2/nodelist.c:255:37: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
../fs/jffs2/nodelist.c:278:38: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
../fs/jffs2/nodelist.c:558:52: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
../fs/jffs2/xattr.c:1247:58: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
../fs/jffs2/xattr.c:1281:65: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
Builds without warnings on all 3 levels of CONFIG_JFFS2_FS_DEBUG.
