4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
commit c58eef061dda7d843dcc0ad6fea7e597d4c377c0 upstream.
Currently the cmd.read_write setting is not initialized so it contains
garbage from the stack. Fix this by setting it to 0 to indicate a
read is required.
