commit c27075772d1f1c8aaf276db9943b35adda8a8b65 upstream.
In a previous fix, I changed the condition on which the timeout of an IRQ is reached from:
if (!ret)
into:
if (ret && !pending)
While having a non-zero return code is usual in the Linux kernel, here ret comes from a wait_for_completion_timeout() which returns 0 when the waiting period is too long.
Hence, the revised condition should be:
if (!ret && !pending)
The faulty patch did not produce any error because of the !pending condition so this change is finally purely cosmetic and does not change the actual driver behavior.
