treewide: use get_random_u32() when possible2022-10-11T23:42:58ZJason A. DonenfeldJason@zx2c4.com2022-10-05T15:43:22Zurn:sha1:a251c17aa558d8e3128a528af5cf8b9d7caae4fd
The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.
