From 4b2b0b9753194cad44d7295c32044b89710efd70 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 23 Apr 2009 16:41:18 +0100 Subject: ROMFS: Advance destination buffer pointer when reading from a blockdev 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.
