* [PATCH] cpufreq: s5pv210: remove unused call of pr_err()

A call of pr_err() was added in v3.1. It was guarded by a check for
CONFIG_PM_VERBOSE. The Kconfig symbol PM_VERBOSE was removed in v3.0. So
this call of pr_err() has never been used. Remove it.

The config symbol itself is not defined and hence could be removed.
However I feel, the
error message could be retained after trimming down the arguments a bit.

What do you meant by this? He already got rid of CONFIG_PM_VERBOSE..

My reasoning is, of course, that never used code can simply be dropped.

But you want to print an error here. That's fine with me. I prefer if
you'd submit a patch that does that, as I have no idea whatsoever why an
error is needed here nor what that error should say.

I do hope you don't mind me prodding you if that takes too long, and
this pointless check of CONFIG_PM_VERBOSE is still here after, say,
another development cycle.

Yes, I agree. However the error message in this case should have been outside
the ifdefs to begin with as it is not an extra information but an
essential message
reporting error condition.

You may just remove the __FILE__ and __LINE__ thing and leave the message as is.

pr_err("Denied access to %s as it is disabled temporarily\n", __func__);

v1 was called "cpufreq: s5pv210: remove unused call of pr_err()". v2
keeps the pr_err() and trims down its arguments, as Sachin requested.

Still untested.
