[PATCH 4.4 077/158] gpu: ipu-v3: ipu-ic: Fix saturation bit offset in TPMEM
From: Greg Kroah-Hartman
Date: Fri Aug 02 2019 - 05:39:37 EST
From: Steve Longerbeam <slongerbeam@xxxxxxxxx>
commit 3d1f62c686acdedf5ed9642b763f3808d6a47d1e upstream.
The saturation bit was being set at bit 9 in the second 32-bit word
of the TPMEM CSC. This isn't correct, the saturation bit is bit 42,
which is bit 10 of the second word.
