staging: xillybus: Removed mmiowb() before mutex_unlock() The relevant sequences consist of two I/O memory writes. The second write depends on the first one. mmiowb() was inserted to make sure that no other thread inserts a "first write" before the current one finished its second. As a mutex protects this critical sequence, mmiowb() is unnecessary. Signed-off-by: Eli Billauer <eli.billauer@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
