cxl: Fix afu_read() not doing finish_wait() on signal or non-blocking If afu_read() returned due to a signal or the AFU file descriptor being opened non-blocking it would not call finish_wait() before returning, which could lead to a crash later when something else wakes up the wait queue. This patch restructures the wait logic to ensure that the cleanup is done correctly. Signed-off-by: Ian Munsie <imunsie@au1.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
