[PATCH 00/38] media sparse/smatch warn fixes

While I was lately relying on Jenkins to report smatch/sparse issues,
I discovered this week that the reports were missing such warnings

I got it fixed already at builder.linuxtv.org, but there are several new
warnings that got added over time.

This series is meant to solve the ones that are reported on x86_64
without pre-building the smatch database.

It should allow receiving cleaner error reports.

While most of the patches are meant to shut up the static analizers,
some contain real bug fixes.
