[PATCH 0/3] clk: imx: imx8qxp-lpcg: Fix the clock-indices parsing

[Abel Vesa]

imx_lpcg_parse_clks_from_dt() trusts the clock-indices property of the
LPCG node. Duplicate entries leak a clock and make the error path
unregister another one twice, and more entries than an LPCG has clock
outputs overflow the on-stack arrays the property and the related
clock names are read into. The first two patches reject both. The last
one makes a failure to read the parent names return an error code
instead of the number of clocks.

Prepared with help from an LLM-based assistant.
