drm: zynqmp_dp: Fix integer overflow in zynqmp_dp_rate_get()HEADdrm-misc-next-2024-12-16for-linux-nextdrm-misc-next
This patch fixes a potential integer overflow in the zynqmp_dp_rate_get()
The issue comes up when the expression
drm_dp_bw_code_to_link_rate(dp->test.bw_code) * 10000 is evaluated using 32-bit
Now the constant is a compatible 64-bit type.
Resolves coverity issues: CID 1636340 and CID 1635811
