clk: tegra: 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. The return value of these functions were never checked in the end anyway, so it is obvious this does not change any functionality :) Cc: Peter De Schrijver <pdeschrijver@nvidia.com> Cc: Prashant Gaikwad <pgaikwad@nvidia.com> Cc: Michael Turquette <mturquette@baylibre.com> Cc: Stephen Boyd <sboyd@kernel.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Jonathan Hunter <jonathanh@nvidia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
