Subject: [PATCH][next] drm/amd/display: Fix sizeof arguments in bw_calcs_init()
Date: Mon, 22 Mar 2021 07:50:50 -0500	[thread overview]
Message-ID: <20210322125050.GA236782@embeddedor> (raw)

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")
