From b9ace0647f044042d88b30ea7bd5130e4ad626a2 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 10 Jun 2025 11:44:20 +0200 Subject: [PATCH] MIPS: SGI-IP27: Delete an unnecessary check before kfree() in hub_domain_free() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It can be known that the function “kfree” performs a null pointer check for its input parameter. It is therefore not needed to repeat such a check before its call. Thus remove a redundant pointer check. The source code was transformed by using the Coccinelle software.
