The patch titled
Subject: checkpatch: improve the indented label test
has been removed from the -mm tree. Its filename was
checkpatch-improve-the-indented-label-test.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Joe Perches <joe@xxxxxxxxxxx>
Subject: checkpatch: improve the indented label test
checkpatch identifies a label only when a terminating colon
immediately follows an identifier.
Bitfield definitions can appear to be labels so ignore any
spaces between the identifier terminating colon and any digit
that may be used to define a bitfield length.
Miscellanea:
o Improve the initial checkpatch comment
o Use the more typical '&&' instead of 'and'
o Require the initial label character to be a non-digit
(Can't use $Ident here because $Ident allows ## concatenation)
o Use $sline instead of $line to ignore comments
o Use '$sline !~ /.../' instead of '!($line =~ /.../)'
