From 3cbf62df3a8ce61cb1aa20b7dae964058988bfdd Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Tue, 26 Oct 2010 14:23:18 -0700 Subject: [PATCH] checkpatch: handle EXPORT_SYMBOL for DEVICE_ATTR and similar Handly definitions similar to below. The definition macro spits out a symbol with a prefix. Add matching of any identifier prefix: DEVICE_ATTR(link_power_management_policy, S_IRUGO | S_IWUSR, ata_scsi_lpm_show, ata_scsi_lpm_put); EXPORT_SYMBOL_GPL(dev_attr_link_power_management_policy); Signed-off-by: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- scripts/checkpatch.pl | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl index d5361e49abad..8ab45b72b396 100755 --- a/scripts/checkpatch.pl +++ b/scripts/checkpatch.pl @@ -1822,8 +1822,17 @@ sub process { !defined $suppress_export{$realline_next} && ($lines[$realline_next - 1] =~ /EXPORT_SYMBOL.*\((.*)\)/ || $lines[$realline_next - 1] =~ /EXPORT_UNUSED_SYMBOL.*\((.*)\)/)) { + # Handle definitions which produce identifiers with + # a prefix: + # XXX(foo); + # EXPORT_SYMBOL(something_foo); my $name = $1; - if ($stat !~ /(?: + if ($stat =~ /^.([A-Z_]+)\s*\(\s*($Ident)/ && + $name =~ /^${Ident}_$2/) { +#print "FOO C name<$name>\n"; + $suppress_export{$realline_next} = 1; + + } elsif ($stat !~ /(?: \n.}\s*$| ^.DEFINE_$Ident\(\Q$name\E\)| ^.DECLARE_$Ident\(\Q$name\E\)| -- 2.20.1
