um: random: Don't initialise hwrng struct with zero
Initialising the hwrng struct with zeros causes a compile-time sparse warning: $ ARCH=um make -j10 W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ... CHECK arch/um/drivers/random.c arch/um/drivers/random.c:31:31: sparse: warning: Using plain integer as NULL pointer Fix the warning by not initialising the hwrng struct with zeros as it is initialised anyway during module init. Fixes: 72d3e093afae ("um: random: Register random as hwrng-core device") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Christopher Obbard <chris.obbard@collabora.com> Signed-off-by: Richard Weinberger <richard@nod.at>
