Subject: [PATCH] leds: mt6370: Remove an unused field in struct mt6370_priv

In "struct mt6370_priv", the 'reg_cfgs' field is unused.

Moreover the "struct reg_cfg" is defined nowhere. Neither in this file, nor
in a global .h file, so it is completely pointless.

Remove it.

Found with cppcheck, unusedStructMember.

So, remove it.

Will do, but this patch does not fix anything.
It is just a clean-up.

I changed all of the commit messages in this disjointed set to flow a
