clk: 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. This cleans up the init code a lot, and there's no need to return an error value based on the debugfs calls, especially as it turns out no one was even looking at that return value. So it obviously wasn't that important :) Cc: Michael Turquette <mturquette@baylibre.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
