[patch 1/4] mtd/sst25l: check for null consistently

[akpm at linux-foundation.org]

From: Dan Carpenter <error27 at gmail.com>

The rest of the function assumes that "data" can be null.  I don't know
the code well enough to say whether it can actually be null, but there is
no harm in checking here.
