Subject: romfs: advance destination buffer pointer when reading from a blockdev
From: David Howells <dhowells@xxxxxxxxxx>
RomFS should advance the destination buffer pointer when reading data from
a blockdev source (the data may be split over multiple blocks, each
requiring its own sb_read() call). Without this, all the data is copied
to the beginning of the output buffer.
