Subject: drm/i915: fix return value check of debugfs_create_file()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f3c5fe979117908fb642ed130ae2cd78cb005931;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drm/i915: fix return value check of debugfs_create_file()

In case of error, the function debugfs_create_file() returns NULL
pointer not ERR_PTR() if debugfs is enabled. The IS_ERR() test in
the return value check should be replaced with NULL test.
