This will disable the clock if we failed to enable it which is clearly not correct. It's also matching a clk_prepare_enable() with a clk_disable() which is going to leave an unbalanced prepare.
s3c_i2sv2_probe is enabling "iis" clock. And s3c2412_i2s_probe is enabling "i2sclk" and "mpll"clock. If, "mpll" clk_prepare_enable fails. We need to disable and free the clock "iis". and devm will handle other clock "i2sclk". In this code we have used "s3c2412_i2s.iis_cclk" for all the clock which is more confusing for me. Please correct me if i am wrong.
OK, they are different clocks. This inconsistent handling seems like a big part of the problem though - it's going to be a source of errors. We're also still only disabling here, not unpreparing, so we're missing something.
