mfd: max77686: do not set i2c client data for rtc i2c client
There is different RTC I2C address for RTC block in MAX77686.
Driver is creating dummy i2c client for this address to access
the register of this IP block.
As there is no call to i2c_get_clientdata() for rtc_i2c client,
there is no need to store pointer and hence removing the call
to set client data for rtc i2c client.

rtc: pcf2123: avoid resetting the clock if possible
pcf2123 data sheet recommends a software reset when the chip
is first powered on. This change avoids resetting the chip
every time the driver is loaded, which has some negative effects.
There are several registers including a clock rate adjustment that really
should survive a reload of the driver (or reboot).
In addition, stopping and restarting the clock to verify the chip is
there is not a good thing once the time is set.
According to the data sheet, the seconds register has a 1 in
the high bit when the voltage has gotten low. We check for this
condition, as well as whether the time retrieved from the chip is
valid. We reset the rtc only if the time is not reliable and valid.
This is sufficient for checking for the presence of the chip,

vmstat: Remove BUG_ON from vmstat_update
If we detect that there is nothing to do just set the flag and do not
check if it was already set before. Races really do not matter. If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.
Since commit
0eb77e988032 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd. This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up. The VM_BUG_ON is therefore misleading and no more
appropriate. Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly. Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.
