diag: Do not write to USB when usb is disconnected

Diag driver tries to write to the USB from different workqueues.
The connect and the disconnect events happen in a different
workqueue. This can lead to a race conditon in setting the SMD
in_busy variables resulting in continuous reads, thereby queueing
up a lot USB writes. This patch protects the SMD in_busy
variables and reduces the latency of USB connect and disconnect
events.

coresight: modify function names and messages

Modify function names and messages to be consistent with other
modules. Modify function names starting with control_* to
event_*, abort_control_tracing to event_trace_user_fault and
abort_tracing_undef_instr to event_trace_undef_instr.

devfreq: governor_cpubw_hwmon: Fix use of decay_rate

The decay rate tunable is used to compute the current averaged bandwidth
use, but the calculated value is never used. Fix this by using the
calculated averaged bandwidth instead of the instantaneous measured
bandwidth when computing the AB and IB votes.

The lenght of the data packet recived in case of

It have to be equal or smaller than the size of the
variable used to hold the data. If this condition
is not met stack-based buffer overflow will occur.

mmc: core: Fix disabling of cache for Hynix cards

Commit 6932a01cd (mmc: card: quirk: disable cache for Hynix card)
claims to disable cache because of data corruption issues when cache
it is enabled. In reality, the patch allows enabling of cache during
card initialization but disallow flushing of cache during suspend or
file system sync operations. This is more dangerous than without
the commit. Move the fixups for disabling cache to mmc_fixups so as
to enable the quirk during initialization itself. Also, remove obvious
warnings everytime card is initialized during runtime resume.
