cpufreq: interactive: fix compiling warnings

The gcc warns like:

  cpufreq_interactive.c:745:6: warning: operation on 'ret' may be undefined [-Wsequence-point]

It was introduced by commit cf0fad49d17cb8273ce555dd5b7afab67d7923bf.

Since sprintf(...) just return 1 (one character) in this case, ret should not changed.
Just discarding the result of sprintf(...) leads to the result that
the committer of cf0fad49d17cb8273ce555dd5b7afab67d7923bf wants.

msm: mdss: properly handle panel on and off

There is some condition that panel off will be called multiple times.
In this case, it was blindly free the gpios that were already released.
This is adding the check to handle this condition.

staging: binder: Change binder mutex to rtmutex.

Surfaceflinger uses binder heavily to receive/send frames from applications
while compositing the screen. Change the binder mutex to an rt mutex to minimize
instances where high priority surfaceflinger binder work is blocked by lower
priority binder ipc.

diag: Reduce error message frequency

Some diag error messages are printed with high frequency. This
cause flooding of kernel logs. Rate limiting these messages will
help reading kernel logs.
