Summary
clk: samsung: Fix UBSAN panic in samsung_clk_init()
Details

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

clk: samsung: Fix UBSAN panic in samsungclkinit()

With UBSANARRAYBOUNDS=y, I'm hitting the below panic due to dereferencing ctx->clk_data.hws before setting ctx->clk_data.num = nr_clks. Move that up to fix the crash.
