Bin Liu 3df7897059 serial: 8250: omap: Move pm_runtime_get_sync ... commit bcc7ba668818dcadd2f1db66b39ed860a63ecf97 upstream. Currently in omap_8250_shutdown, the dma->rx_running flag is set to zero in omap_8250_rx_dma_flush. Next pm_runtime_get_sync is called, which is a runtime resume call stack which can re-set the flag. When the call omap_8250_shutdown returns, the flag is expected to be UN-SET, but this is not the case. This is causing issues the next time UART is re-opened and omap_8250_rx_dma is called. Fix by moving pm_runtime_get_sync before the omap_8250_rx_dma_flush. cc: stable@vger.kernel.org Fixes: 0e31c8d173ab ("tty: serial: 8250_omap: add custom DMA-RX callback") Signed-off-by: Bin Liu <b-liu@ti.com> [Judith: Add commit message] Signed-off-by: Judith Mendez <jm@ti.com> Reviewed-by: Kevin Hilman <khilman@baylibre.com> Tested-by: Kevin Hilman <khilman@baylibre.com> Link: https://lore.kernel.org/r/20241031172315.453750-1-jm@ti.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2024-12-17 13:24:19 +01:00
