Signed-off-by: Lee Jones -
During probe the sec-core driver allocates dummy I2C device for RTC with
i2c_new_dummy() but return value is not checked. In case of error
(i2c_new_device(): memory allocation failure or I2C address cannot be
used) this function returns NULL which is later used by
devm_regmap_init_i2c() or i2c_unregister_device().If i2c_new_dummy() fails for RTC device, fail also the probe for main
MFD driver.Cc: stable@vger.kernel.org

Add support for S2MPS14 PMIC device to the MFD sec-core driver.
The S2MPS14 is similar to S2MPS11 but it has fewer regulators, two
clocks instead of three and a little different registers layout.Signed-off-by: Krzysztof Kozlowski

The S2MPS11 RTC has two alarms: alarm0 and alarm1 (corresponding

A single line patch fixing a regression that was introduced in 3.13 in the
reworking of the mxs touch screen and ADC drivers to be interrupt rather
than polling driven. It resulted in a stray double reporting of the release

Page table entries on ARM64 are 64 bits, and some pte functions such as
pte_dirty return a bitwise-and of a flag with the pte value. If the
flag to be tested resides in the upper 32 bits of the pte, then we run
into the danger of the result being dropped if downcast.For example:
gather_stats(page, md, pte_dirty(*pte), 1);
where pte_dirty(*pte) is downcast to an int.This patch adds a double logical invert to all the pte_ accessors to
ensure predictable downcasting.Signed-off-by: Steve Capper

When remapping a block to the cache's fast device that is larger than
2TB we must not truncate the destination sector to 32bits. The 32bit
temporary result of from_cblock() was being overflowed in
