Subject: [PATCH] perf/thunderx2: Replace devm_kasprintf() call by devm_kstrdup() in tx2_uncore_pmu_register()
Date: Wed, 16 Apr 2025 17:28:44 +0200 [thread overview]
Message-ID: <d4516add-45ad-412a-b9bf-ee21afae3da9@web.de> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 16 Apr 2025 17:15:54 +0200
Use a devm_kstrdup() call instead of a devm_kasprintf() call
in this function implementation because only a single string
should be copied.
The source code was transformed by using the Coccinelle software.
