Alessandro Carminati 0d6a46a9a3 clk: Sanitize possible_parent_show to Handle Return Value of of_clk_get_parent_name 
commit ceb87a361d0b079ecbc7d2831618c19087f304a9 upstream.

In the possible_parent_show function, ensure proper handling of the return
value from of_clk_get_parent_name to prevent potential issues arising from
a NULL return.
The current implementation invokes seq_puts directly on the result of
of_clk_get_parent_name without verifying the return value, which can lead
to kernel panic if the function returns NULL.

This patch addresses the concern by introducing a check on the return
value of of_clk_get_parent_name. If the return value is not NULL, the
function proceeds to call seq_puts, providing the returned value as
argument.
However, if of_clk_get_parent_name returns NULL, the function provides a
static string as argument, avoiding the panic.

Fixes: 1ccc0ddf046a ("clk: Use seq_puts() in possible_parent_show()")
