[PATCH 2/5] mips: ralink: no need to check return value of debugfs_create functions

From: Greg Kroah-Hartman
Date: Tue Jan 22 2019 - 09:58:32 EST


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.
