From: Greg Kroah-Hartman Date: Thu, 13 Jun 2019 18:38:30 +0000 (+0200) Subject: thermal: intel: no need to check return value of debugfs_create functions X-Git-Tag: v5.4.17~3171^2~56 X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=72c9f26b583c54e89de386e0eb63398c07d95cfa;p=arm%2Flinux.git thermal: intel: no need to check return value of debugfs_create functions When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.
