Subject: drivers/base/devtmpfs.c: don't pretend path is const in delete_path
X-Git-Tag: v4.20-rc1~108^2~6

drivers/base/devtmpfs.c: don't pretend path is const in delete_path

path is the result of kstrdup, and we repeatedly call strrchr on it,
modifying it through the returned pointer. So there's no reason to
pretend path is const.
