[PATCH 0/2] fix the issue when xfer by spi-altera

2020-12-28 Thread Xu Yilun

When doing spi xfer by spi-altera, divide by 0 exception happens in spi_transfer_wait(), This is because the xfer->speed_hz is always clamped to 0 by spi->controller->max_speed_hz, the feature is introduced in: commit 9326e4f1e5dd ("spi: Limit the spi device max speed to controller's max speed")
