From ae16cc18f37bcdea7d4ef57a5e526a60b09a1506 Mon Sep 17 00:00:00 2001 From: Patrice Chotard Date: Wed, 11 May 2022 09:46:44 +0200 Subject: [PATCH] spi: stm32-qspi: Remove SR_BUSY bit check before sending command Waiting for SR_BUSY bit when receiving a new command is not needed. SR_BUSY bit is already managed in the previous command treatment.
