5a2cf05422 mfd: ene-kb3930: Make local symbol 'kb3930_power_off' static 
The sparse tool complains as follows:

drivers/mfd/ene-kb3930.c:36:15: warning: symbol 'kb3930_power_off' was not declared. Should it be static?

The symbol is not used outside of this file.

e9063fee2b mfd: ene-kb3930: Drop of_match_ptr from of_device_id table 
The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it is not relevant here).  This fixes
compile warning (!CONFIG_OF on x86_64):

  drivers/mfd/ene-kb3930.c:194:34: warning: ‘kb3930_dt_ids’ defined but not used [-Wunused-const-variable=]

ede6b2d1df mfd: ene-kb3930: Add driver for ENE KB3930 Embedded Controller 
This driver provides access to the EC RAM of said embedded controller
attached to the I2C bus as well as optionally supporting its slightly weird
power-off/restart protocol.

A particular implementation of the EC firmware can be identified by a
model byte. If this driver identifies the Dell Ariel platform, it
registers the appropriate cells.
