OPP: of: Fix potential multiplication overflow when calculating freq

Browse source

The multiplication be32_to_cpup(val++) * 1000 is performed using 32 bit
unsigned integers and hence uses a 32 bit multiplication; this will
overflow if be32_to_cpup(val++) is greater than 4294967 (which is
very unlikely at present). The result is assigned to an unsigned long
(which is a 64 bit value on 64 bit systems), so fix this potential
overflow by casting the first operand of the multiplication to
an unsigned int.

Fixes: b496dfbc94 ("PM / OPP: Initialize OPP table from device tree")
