Subject: [PATCH][next] drm/amd/display: Fix sizeof arguments in bw_calcs_init()
The wrong sizeof values are currently being used as arguments to kzalloc().
Fix this by using the right arguments *dceip and *vbios, correspondingly.
Addresses-Coverity-ID: 1502901 ("Wrong sizeof argument")
Fixes: fca1e079055e ("drm/amd/display/dc/calcs/dce_calcs: Remove some large variables from the stack")
