Frans Meulenbroeks aac9fe9b46 hwmon: (ltc4261) set data->valid to 0 if error
If there is an error it is better to set data->valid to 0
so the next call to ltc4261_update_device will always be
executed.

Björn Gerhart f58c44e698 hwmon: (f75375s) Add support for F75387SG/RG
Fintek F75387SG/RG is mostly compatible to F75373/F75375. Add support for it
to the F75375S driver.

Fan support for F75387SG/RG has been implemented but not tested.

pwmX_mode and pwmX_enable are not initialized if no platform data is provided to
the driver. Read chip configuration at driver initialization time and initialize

Accepted value range for PWM modes was 0..4, even though only 0..3 is

Guenter Roeck 740f6be3cc hwmon: (f75375s) Use standard sysfs attribute names
The driver uses non-standard sysfs attribute names for maximum and target fan

Replace non-standard attribute names with standard attribute names.

Guenter Roeck 56badacb92 hwmon: (pmbus/zl6100) Only instantiate external temperature sensor if enabled
BMR4xx devices don't have an external temperature sensor,
and instantiating it does not provide value anyway if it is disabled.
Only instantiate it if it is enabled.

Also optimize wait time between I2C chip accesses in the probe function, and
replace unnecessary check for support for I2C_FUNC_SMBUS_READ_BYTE_DATA with
now required support for I2C_FUNC_SMBUS_READ_WORD_DATA.

Simon Glass 27edacac7d ARM: 7267/1: Remove BUILD_BUG_ON from asm/bug.h
BUILD_BUG_ON is defined in linux/kernel.h but that is not included by the
asm/bug.h header which uses it. This causes a build error:

...include/linux/mtd/map.h:408:3: error: implicit declaration of function
'BUILD_BUG_ON' [-Werror=implicit-function-declaration]

The check is not essential and is not present for other architectures, so
just remove it.

Remove the now empty arch_reset() from all the mach/system.h includes,

no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.
