Erwan Le Ray 59ed254dd3 serial: stm32: re-introduce an irq flag condition in usart_receive_chars ... [ Upstream commit cc58d0a3f0 ] Re-introduce an irq flag condition in usart_receive_chars. This condition has been deleted by commit 75f4e830fa ("serial: do not restore interrupt state in sysrq helper"). This code was present to handle threaded case, and has been removed because it is no more needed in this case. Nevertheless an irq safe lock is still needed in some cases, when DMA should be stopped to receive errors or breaks in PIO mode. This patch is a precursor to the complete rework or stm32 serial driver DMA implementation.
