The ISL12026 is a combination RTC and EEPROM device with I2C
interface. The standard RTC driver interface is provided. The EEPROM
is accessed via the NVMEM interface via the "eeprom0" directory in the
sysfs entry for the device.

Of course, your patch still doesn't allow for "we claim to be skylake

Fix the dup_sg_table function to initialize the dma_address of the new
sg list entries instead of the source dma_address entries.
Since ION duplicates the sg_list this issue does not appear to result in
an actual bug.

Hello,
This patchset contains some improvements for the Kconfig help text check in
scripts/checkconfig.pl:
- Commits 1 and 2 make the check more robust by checking menuconfig symbols
and choices as well as symbols defined with 'config', and by making the
detection of definition boundaries
IMO, we should discourage '---help---' for new help texts, even in cases
where it would be consistent with other help texts in the file. This
will help if we ever want to get rid of '---help---' in the future.
Also simplify the code to only check for exactly '---help---'. Since
commit c2264564df3d
The check for a missing or short help text only considers symbols with a
prompt, but doesn't recognize any of the following as a prompt:
bool 'foo'
tristate 'foo'
prompt "foo"
prompt 'foo'
Make the check recognize those too.

Currently, only Kconfig symbols are checked for a missing or short help
text, and are only checked if they are defined with the 'config'
keyword.
To make the check more general, extend it to also check help texts for
choices and for symbols defined with the 'menuconfig' keyword.
This increases th
