Subject: [PATCH v4 06/15] drm/amdgpu: validate suspend before function call
Date: Thu, 17 Oct 2024 15:36:06 +0530 [thread overview]
Message-ID: <20241017100615.1492144-7-sunil.khatri@amd.com> (raw)
In-Reply-To: <20241017100615.1492144-1-sunil.khatri@amd.com>
Before making a function call to suspend, validate
the function pointer like we do in sw_init.
