intel_th: gth: Remove commented-out code
There's a commented-out function in the GTH driver that's a leftover from previous versions of the driver, where we tried to inherit the pre-existing configuration, which didn't prove to be a sound idea. This patch removes the function. No functional changes. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
