The patch titled
Subject: checkpatch: add --kconfig-prefix
has been removed from the -mm tree. Its filename was
checkpatch-add-kconfig-prefix.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Jerome Forissier <jerome@forissier.org>
Subject: checkpatch: add --kconfig-prefix
Kconfig allows to customize the CONFIG_ prefix via the $CONFIG_
environment variable. Out-of-tree projects may therefore use Kconfig with
a different prefix, or they may use a custom configuration tool which does
not use the CONFIG_ prefix at all. Such projects may still want to adhere
to the Linux kernel coding style and run checkpatch.pl.
One example is OP-TEE [1] which does not use Kconfig but does have
configuration options prefixed with CFG_. It also mostly follows the
kernel coding style and therefore being able to use checkpatch is quite
valuable.
To make this possible, add the --kconfig-prefix command line option.
