The patch titled
Subject: checkpatch: add PREFER_IS_ENABLED test
has been removed from the -mm tree. Its filename was
checkpatch-add-prefer_is_enabled-test.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Joe Perches <joe@xxxxxxxxxxx>
Subject: checkpatch: add PREFER_IS_ENABLED test
Using #if defined CONFIG_<FOO> || defined CONFIG_<FOO>_MODULE is
more verbose than necessary and IS_ENABLED(CONFIG_<FOO>) is preferred.
So add a test and a message for it.
--fix it to if desired.
