4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Sifan Naeem <sifan.na...@imgtec.com>
commit 5728d95f2458887ae3d95547c04352bba5080ad6 upstream.
Using % can be slow depending on the architecture.
Using DIV_ROUND_UP is nicer and more efficient way to do it.
Fixes: commit 27bce457d588 ("i2c: img-scb: Add Imagination Technologies I2C SCB
driver")
