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.
