From: Longlong Xia Date: Fri, 10 Feb 2023 09:54:44 +0000 (+0000) Subject: devtmpfs: remove return value of devtmpfs_delete_node() X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9d3fe6aa6b9517408064c7c3134187e8ec77dbf7;p=users%2Fjedix%2Flinux-maple.git devtmpfs: remove return value of devtmpfs_delete_node() The only caller of device_del() does not check the return value. And there's nothing we can do when cleaning things up on a remove path. Let's make it a void function.
