Yufen Yu 86e74ca9fd floppy: check_events callback should not return a negative number ...

[ Upstream commit 96d7cb932e ]

floppy_check_events() is supposed to return bit flags to say which
events occured. We should return zero to say that no event flags are
set.  Only BIT(0) and BIT(1) are used in the caller. And .check_events
interface also expect to return an unsigned int value.

However, after commit a0c80efe59, it may return -EINTR (-4u).
Here, both BIT(0) and BIT(1) are cleared. So this patch shouldn't
affect runtime, but it obviously is still worth fixing.
