What it is

In the Linux kernel, the following vulnerability has been resolved:

clk: qcom: gcc-sm6350: Add missing parent_map for two clocks

If a clk_rcg2 has a parent, it should also have parent_map defined,

otherwise we'll get a NULL pointer dereference when calling clk_set_rate

like the following:

[ 3.388105] Call trace:

[ 3.390664] qcom_find_src_index+0x3c/0x70 (P)

[ 3.395301] qcom_find_src_index+0x1c/0x70 (L)

[ 3.399934] _freq_tbl_determine_rate+0x48/0x100

[ 3.404753] clk_rcg2_determine_rate+0x1c/0x28

[ 3.409387] clk_core_determine_round_nolock+0x58/0xe4

[ 3.421414] clk_core_round_rate_nolock+0x48/0xfc

[ 3.432974] clk_core_round_rate_nolock+0xd0/0xfc

[ 3.444483] clk_core_set_rate_nolock+0x8c/0x300

[ 3.455886] clk_set_rate+0x38/0x14c

Add the parent_map property for two clocks where it's missing and also

un-inline the parent_data as well to keep the matching parent_map and

parent_data together.
