Subject: [PATCH] drm/i915/gvt: use DEFINE_DEBUGFS_ATTRIBUTE with debugfs_create_file_unsafe()
Date: Fri, 30 Oct 2020 08:59:45 +0530	[thread overview]
Message-ID: <20201030032945.GA274850@my--box> (raw)

Using DEFINE_DEBUGFS_ATTRIBUTE macro with debugfs_create_file_unsafe()
function in place of the debugfs_create_file() function will make the
file operation struct "reset" aware of the file's lifetime. Additional
details here: https://lists.archive.carbon60.com/linux/kernel/2369498

Issue reported by Coccinelle script:
scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci
