[PATCH 3/3] spi: stm32-qspi: Remove SR_BUSY bit check before sending command

From: patrice.chotard
Date: Wed May 11 2022 - 03:47:27 EST


From: Patrice Chotard <patrice.chotard@xxxxxxxxxxx>

Waiting for SR_BUSY bit when receiving a new command is not needed.
SR_BUSY bit is already managed in the previous command treatment.
