Subject: [PATCH] drm/amdkfd: Use ARRAY_SIZE macro in kfd_build_sysfs_node_entry
Date: Thu, 18 Jan 2018 18:39:55 -0600 [thread overview]
Message-ID: <20180119003955.GA28885@embeddedor.com> (raw)
Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element.
This issue was detected with the help of Coccinelle.
