* A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kcalloc".
This issue was detected by using the Coccinelle software.
* Replace the specification of a data type by a pointer dereference
to make the corresponding size determination a bit safer according to
the Linux coding style convention.

cs2000 can select Static/Dynamic ratio based Frequency Synthesizer
Mode, it can select 20.12 High Multiplier interpret for 32-bit
User Defined Ratio if Dynamic ratio mode. Otherwise it should select
12.20 High Accuracy mode.
Current cs2000 is supporting Static ratio mode only, so it should
select 12.20 High Accuracy mode, not 20.12 High Multiplier mode.
This patch fixes it.

Note is that current cs2000 driver is using/supporting only ratio0

Due to timing requirements, TI and Conexant manage the audio
reference clock from their ASoC codec drivers using the "mclk"
string. This patch adds another lookup for the "pmc_plt_clk_3"
clock to avoid Intel-specific tests in those codec drivers and
use code as-is.
To avoid a leak, clk_add_alias() is not used in this patch.
Instead the lookup is created manually as part of the .probe()
step and dropped in the .remove() step.
"pmc_plt_clk_3" is used exclusively for audio on all known
Baytrail/CherryTrail designs and is e.g. routed on the MCLK
(pin 26) of the MinnowBoardMAX Turbot LSE connector.

Currently, the rcutorture scripting will give an error message if
running a duplicate scenario that happens also to have a non-existent
build directory (b1, b2, ... in the rcutorture directory). Worse yet, if
the build directory has already been created and used for a real build,
the script will silently grab the wrong Kconfig fragment, which could
cause confusion to the poor sap (me) analyzing old test results. At
least the actual test runs correctly...
This commit therefore accesses the Kconfig fragment from the results
directory corresponding to the first of the duplicate scenarios, for
which a build was actually carried out. This prevents both the messages
and at least one form of later confusion.

sparse is unhappy about this code in hlist_add_tail_rcu:
struct hlist_node *i, *last = NULL;
for (i = hlist_first_rcu(h); i; i = hlist_next_rcu(i))
last = i;
This is because hlist_next_rcu and hlist_next_rcu return
__rcu pointers.
It's a false positive - it's a write side primitive and so
does not need to be called in a read side critical section.
The following trivial patch disables the warning
without changing the behaviour in any way.
Note: __hlist_for_each_rcu would also remove the warning but it would be
confusing since it calls rcu_derefence and is designed to run in the rcu
read side critical section.
