ide: also reset io_buffer_index for writes
Currenly the code only resets the io_buffer_index field for reads, but the code seems to expect this for all types of I/O. I guess we simply don't hit large enough transfers that would require this often enough. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
