[PATCH] fbdev: omap2: no need to check return value of debugfs_create functions

[Tony Lindgren]

* Greg Kroah-Hartman <gregkh at linuxfoundation.org> [190122 15:28]:
> 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.
