crypto: chtls - use 64-bit arithmetic instead of 32-bit
Cast *val* to u64 in order to give the compiler complete information about the proper arithmetic to use. Notice that such variable is used in a context that expects an expression of type u64 (64 bits, unsigned) and the following expression is currently being evaluated using 32-bit arithmetic: val << bit_pos Addresses-Coverity-ID: 1467425 ("Unintentional integer overflow") Signed-off-by: Gustavo A.
