The Medion Lifetab S10346 is a x86 tablet which ships with Android x86 as
factory OS. The Android x86 kernel fork ignores I2C devices described in
the DSDT, except for the PMIC and Audio codecs.

As usual the Medion Lifetab S10346's DSDT contains a bunch of extra I2C
devices which are not actually there, causing various resource conflicts.
Add an ACPI_QUIRK_SKIP_I2C_CLIENTS quirk for the Medion Lifetab S10346 to
the acpi_quirk_skip_dmi_ids table to woraround this.

Using pr_cont() in the tasks freezing code related to system-wide
suspend and hibernation is problematic, because the continuation
messages printed there are susceptible to interspersing with other
unrelated messages which results in output that is hard to
understand.

Address this issue by modifying try_to_freeze_tasks() to print
messages that don't require continuations and adjusting its
callers accordingly.

Because rpm_callback() is a wrapper around __rpm_callback(), and the
only caller of it after the change eliminating an invocation of it
from rpm_idle(), move the former next to the latter to make the code
a bit easier to follow.

Calling __rpm_callback() from rpm_idle() after adding device links
support to the former is a clear mistake.

Not only it causes rpm_idle() to carry out unnecessary actions, but it
is also against the assumption regarding the stability of PM-runtime
status across __rpm_callback() invocations, because rpm_suspend() and
rpm_resume() may run in parallel with __rpm_callback() when it is called
by rpm_idle() and the device's PM-runtime status can be updated by any
of them.
