the Linux kernel, the following vulnerability has been resolved:\n\nclk: qcom: ipq8074: fix PCI-E clock oops\n\nFix PCI-E clock related kernel oops that are caused by a missing clock\nparent.\n\npcie0_rchng_clk_src has num_parents set to 2 but only one parent is\nactually set via parent_hws, it should also have \"XO\" defined.\nThis will cause the kernel to panic on a NULL pointer in\nclk_core_get_parent_by_index().\n\nSo, to fix this utilize clk_parent_data to provide gcc_xo_gpll0 parent\ndata.\nSince there is already an existing static const char * const gcc_xo_gpll0[]\nused to provide the same parents via parent_names convert those users to\nclk_parent_data as well.\n\nWithout this earlycon is needed to even catch the OOPS as it will reset\nthe board
