If anyone has any objections, please let me know. ------------------ From: Luis R. Rodriguez commit 880444e214cfd293a2e8cc4bd3505f7ffa6ce33a upstream. Error that we expect should not be spilled to stdout. Without this we get: ./fw_filesystem.sh: line 58: printf: write error: Invalid argument ./fw_filesystem.sh: line 63: printf: write error: No such device ./fw_filesystem.sh: line 69: echo: write error: No such file or directory ./fw_filesystem.sh: filesystem loading works ./fw_filesystem.sh: async filesystem loading works With it: ./fw_filesystem.sh: filesystem loading works ./fw_filesystem.sh: async filesystem loading works Signed-off-by: Luis R.
