commit 1b8b68b05d1868404316d32e20782b00442aba90 upstream
All error handling paths in this function 'goto err' except this one.
If one of the 2 previous memory allocations fails, we should go through
the existing error handling path. Otherwise there is an unbalanced
pm_runtime_enable()/pm_runtime_disable().
Fixes: dd55ff8346a9 ("ASoC: davinci-mcasp: Add set_tdm_slots() support")
