[PATCH 0/4] tree-wide: fix comparison to bitshift when dealing with a mask

[Wolfram Sang]

In one Renesas driver, I found a typo which turned an intended bit shift ('<<')
into a comparison ('<'). Because this is a subtle issue, I looked tree wide for
similar patterns. This small patch series is the outcome.

Buildbot and checkpatch are happy. Only compile-tested. To be applied
individually per sub-system, I think. I'd think only the net: amd: patch needs
to be conisdered for stable, but I leave this to people who actually know this
driver.

CCing Dan. Maybe he has an idea how to add a test to smatch? In my setup, only
cppcheck reported a 'coding style' issue with a low prio.
