Subject: [PATCH] spi: stm32-qspi: remove signal sensitive on completion
From: Ludovic Barre <ludovic.barre@...com>
On umount step a sigkill signal is set (without user specific
action), due to sigkill signal the completion will be interrupted and
the data transfer can't be finished if a sync is needed.
