For security, I will release this pointer only on error paths in this function.
Do you tend to release objects (which are referenced by pointers)?
I just found that clk is referenced by pclk in this function. When clk is freed, pclk will be allocated in gm20b_clk_new_speedo0(). Thus we should not release clk in this function and there is no bug here. Thank you for reminding me!
