The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".The Coccinelle script used for this was:

Currently, lp55xx_of_populate_pdata() allocates lp55xx_platform_data if
it's null. And it parses the DT and copies values into the
'client->dev.platform_data'. This may have architectural issue.
Platform data is configurable through the DT or I2C board info inside the
platform area. However, lp55xx common driver changes this configuration
when it is loaded. So 'client->dev.platform_data' is not null anymore.
Eventually, the driver initialization is not identical when it's unloaded
and loaded again.
The lp55xx common driver should use the private data, 'lp55xx_chip->pdata'
instead of changing the original platform data.So, lp55xx_of_populate_pdata() is modified as follows.
* Do not update 'dev->platform_data'. Return the pointer of new allocated
lp55xx_platform_data. Then the driver points it to private data,
'lp55xx_chip->pdata'.
* Each lp55xx driver checks the pointer and handles an error case.Then, original platform data configuration will be kept regardless of
loading or unloading the driver.
The driver allocates the memory and copies them from the DT if it's NULL.
After the driver is loaded again, 'client->dev.platform_data' is same as
initial load, so the driver is initialized identically.Cc: Toshi Kikuchi

Whenever the engine is loaded by the user-application, the operation mode is
reset first. But it has a problem in case of multiple engine used because
previous engine settings are cleared.
The driver should update not whole 8bits but each engine bit by masking.On the other hands, whole engines should be reset when the driver is unloaded
and on initializing the LP5523 driver.
So, new functions are used for this handling - lp5521/5523_stop_all_engines().Cc: Pali Rohár

may cause an application confict, engineN_mode and engineN_load.
This interface should be maintained for compatibility.Restored device attributes are 'engineN_mode' and 'engineN_load'.
A 'selftest' attribute macro is replaced with LP55xx common macro.Use a mutex in lp5521_update_program_memory()
: This function is called when an user-application writes a 'engineN_load' file
or pattern data is loaded from generic firmware interface.
So, writing program memory should be protected.
If an error occurs on accessing this area, just it returns as -EINVAL quickly.
This error code is exact same as old driver function, lp5521_do_store_load()
because it should be kept for an user-application compatibility.
Even the driver is changed, we can use the application without re-compiling
sources.'led_pattern' attribute is not included
: engineN_mode and _load were created for custom user-application.
'led_pattern' is an exception. I added this attribute not for custom application

Now LP55xx provides automatic clock detection API, lp55xx_is_extclk_used().
The clock configuration can be done by the driver itself.(a) Concept
The default value is set by each driver with clock selection.
The internal clock selection bit is updated in case that the external clock
is not detected or clock rate is not 32KHz.(b) Change on LP55xx platform data
The clock configuration is done automatically, so no need to define
'update_config' in the platform side.
Correlated information are removed in the documentations and header.(c) Definitions moved from header to driver files

LP5521/5523 reset device functions are moved to lp55xx common driver.
Value of register address and value are chip dependent.
Those are configured in each driver.
In init function, reset command is executed.Signed-off-by: Milo(Woogyom) Kim

LP5521/5523 platform data functions are moved to lp55xx common driver.

This patch is a preceding step for making common lp55xx init function.
LP5521_REG_R_CURRENT register code moved:
Chip specific code moved from lp5521_init_device() to lp5521_configure().Remove engine init function:
LP5521 has internal program engines which are used for running LED patterns.
(blinking, ramp up/down and other emotional visual effects)
Engine initialization is done by reset command in lp5521_init_device().
Remove this duplicate code.Return code:
Do not use 'OR' arithmetic for the result.
If some error occus, just return it.Enable latency:
Use explicit named function, lp5521_wait_enable_done().
According to the datasheet, 500us is guaranteed time.
Thus wait time is changed from 1000us to 500us.Signed-off-by: Milo(Woogyom) Kim
