From 8e206c6415cac4cd32d9a777597dba958f60a6ed Mon Sep 17 00:00:00 2001 From: Larisa Grigore Date: Thu, 28 Aug 2025 11:14:42 +0100 Subject: [PATCH] spi: spi-fsl-lpspi: Reset FIFO and disable module on transfer abort [ Upstream commit e811b088a3641861fc9d2b2b840efc61a0f1907d ] In DMA mode fsl_lpspi_reset() is always called at the end, even when the transfer is aborted. In PIO mode aborts skip the reset leaving the FIFO filled and the module enabled. Fix it by always calling fsl_lpspi_reset().
