From 4c404487aa3d26bf7a7e16f8545778385e06d839 Mon Sep 17 00:00:00 2001 From: David Cross Date: Fri, 10 Sep 2010 16:55:53 -0700 Subject: [PATCH] staging: west bridge: cyasgadget, remove file system / vfs calls This patch remove file system specific (fat_get_block) and vfs calls from the cyasgadget driver. The current implementation expects user space to write the file (open, seek to end, 1 byte write), followed by a call to clear the dirty pages from the the page cache.
