+Subject: [PATCH] mtd: spinand: macronix: use scratch buffer for DMA operation
+
+The mx35lf1ge4ab_get_eccsr() function uses an SPI DMA operation to
+read the eccsr, hence the buffer should not be on stack. Since commit
+380583227c0c7f ("spi: spi-mem: Add extra sanity checks on the op param")
+the kernel emmits a warning and blocks such operations.
+
+Use the scratch buffer to get eccsr instead of trying to directly read
+into a stack-allocated variable.
