Would "contains an ecc-engine property" be better English?

I am not sure what is the rule when it comes to plain English with
variable names. However if you agree, no need to re-send the series, I
can fix it when applying.

BTW, I added hw ECC engines support to my generic ECC engine
implementation, but migrating the whole raw NAND subsystem (using I/O
requests like in the SPI-NAND core, adding prepare/finish_io_req hooks)
is going to be much more invasive than initially expected, so I am not
sure I will finish the migration any time soon.


Thanks,
Miquèl
