The 'res' pointer passed to devm_clk_match() is a pointer to struct
devm_clk_state after commit abae8e57e49a ("clk: generalize
devm_clk_get() a bit"). Update the logic here to convert the void
pointer to the right type so that this is cleaner. Note that this
doesn't actually change anything due to how struct devm_clk_state is
defined to have a struct clk pointer as the first member.
Given we're cleaning things up, split the WARN_ON() into two different
conditions to provide clarity about which condition is false. Also move
the WARN_ON to the conditional so that the compiler is hinted that all
this code is unlikely().
