Add missing iounmap in error handling code, in a case where the function
already preforms iounmap on some other execution path.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression e;
statement S,S1;
int ret;
@@
e = \(ioremap\|ioremap_nocache\)(...)
... when != iounmap(e)
if (<+...e...+>) S
... when any
when != iounmap(e)
*if (...)
{ ... when != iounmap(e)
return ...; }
... when any
iounmap(e);
// </smpl>

If the frontend is in idle state, don't call get_frontend.
Calling get_frontend() when the device is not tuned may
result in wrong parameters to be returned to the
userspace.
I was tempted to not call get_frontend() at all, except
inside the dvb frontend thread, but this won't work for
all cases. The ISDB-T specs (ABNT NBR 15601 and ARIB
STD-B31) allow the broadcaster to dynamically change the
channel specs at runtime. That means that an ISDB-T optimized
application may want/need to monitor the TMCC tables, decoded
at the frontends via get_frontend call.
So, let's do the simpler change here.
Eventually, the logic could be changed to work only if
the device is tuned and has lock, but, even so, the
lock is also standard-dependent. For ISDB-T, the right
lock to wait is that the demod has TMCC lock. So, drivers
may need to implement some logic to detect if the get_frontend
info was retrieved or not.

This reverts commit d2a7009f0b.
J. R. Okajima explains:
"After this commit, I am afraid access(2) on NFS may not work
correctly. The scenario based upon my guess.
- access(2) overrides the credentials.
- calls inode_permission() -- ... -- generic_permission() --
ns_capable().
- while the old ns_capable() calls security_capable(current_cred()),
the new ns_capable() calls has_ns_capability(current) --
security_capable(__task_cred(t)).
current_cred() returns current->cred which is effective (overridden)
credentials, but __task_cred(current) returns current->real_cred (the
NFSD's credential). And the overridden credentials by access(2) lost."

For UP processor, it is likely that no _MAT method or MADT table defined.
So currently acpi_get_cpuid(...) always return -1 for UP processor.
This is wrong. It should return valid value for CPU0.
In the other hand, BIOS may define multiple CPU handles even for UP
processor, for example
Scope (_PR)
{
Processor (CPU0, 0x00, 0x00000410, 0x06) {}
Processor (CPU1, 0x01, 0x00000410, 0x06) {}
Processor (CPU2, 0x02, 0x00000410, 0x06) {}
Processor (CPU3, 0x03, 0x00000410, 0x06) {}
}
We should only return valid value for CPU0's acpi handle.
And return invalid value for others.

smp_call_function() only lets all other CPUs execute a specific function,
while we expect all CPUs do in intel_idle. Without the fix, we could have
one cpu which has auto_demotion enabled or has no broadcast timer setup.
Usually we don't see impact because auto demotion just harms power and the
intel_idle init is called in CPU 0, where boradcast timer delivers
interrupt, but this still could be a problem.
