Subject: dfu:core: Export dfu_{get|free}_buf functions
X-Git-Tag: v2014.01-rc1~207^2~23
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d42782631d59ea12251629bb827f725ef4dfddf6;p=kernel%2Fu-boot.git

dfu:core: Export dfu_{get|free}_buf functions

Define the dfu_get_buf() and dfu_free_buf() as global functions.
They are necessary for zero copy buffer management, when DFU backend is
used for storing data.
