Re: [PATCH] mtd: nand: omap: ecc.correct: omap_elm_correct_data: return number of bit-flips detected in erased-page

[Ezequiel Garcia <ezequiel.garcia@free-electrons.com>]

Pekon,

I'm not sure we need such a detailed subject. Just "mtd: nand: omap:
Return detected bitflip count" should be enough.

This goes for your other patches. It's just a nitpick, of course,
but it's good to have commit log consistency.

Remove these extra whitespace.

And this extra tab.

We don't need a piece of code here, we can see that in the patch itself.
The commit log should be a text explaining what you are doing, why you are doing
it and perhaps the impact it has.

I suggest that you clean-up this a bit and resend it.
