f66a49766fdfcb8186056bd44a407594c6a3d5ff 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.
