[Linux-stm32] [PATCH] spi: stm32-qspi: remove signal sensitive on completion

[Ludovic Barre]

From: Ludovic Barre <ludovic.barre at st.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.
