[lvc-project] [PATCH] AF9005: fix typo in the bitmask size

[Fedor Pchelkin]

Hi,

The same patch was sent twice [1,2]. Why? If something has changed, it's
good to denote the next version as v2 and briefly explain the v1->v2
changes in the zone after `---`.

Even for the one-line fixes there should be some brief explanation on
*why* there is a problem and why it should be fixed, i.e. why there is
a typo in the code.

I guess the problem looks obvious here but still there may be some
useful information (if any) provided to the changelog.

The blank line between Fixes and Signed-off-by is unwanted.

git format-patch usually generates a `---` line here after the end of
the commit message.

Please take a look at [3].
