drm/amd/display: Fix potential integer overflow
Fix potential integer overflow by casting actual_calculated_clock_100hz 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: actual_calculated_clock_100hz * post_divider Fixes: 7a03fdf6 ("drm/amd/display: fix 64bit division issue on 32bit OS") Addresses-Coverity-ID: 1501691 ("Unintentional integer overflow") Signed-off-by:Gustavo A.
