[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Xiu Jianfeng <xiujianfeng@xxxxxxxxxx>

[ Upstream commit cfd3ffb36f0d566846163118651d868e607300ba ]

If st_clk_register_quadfs_pll() fails, @lock should be freed before goto
@err_exit, otherwise will cause meory leak issue, fix it.
