Subject: [PATCH] esp: use correct type for esp_dma_enable() in
sysbus_esp_gpio_demux()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The call to esp_dma_enable() was being made with the SYSBUS_ESP type instead of
the ESP type. This meant that when GPIO 1 was being used to trigger a DMA
request from an external DMA controller, the setting of ESPState's dma_enabled
field would clobber unknown memory whilst the dma_cb callback pointer would
typically return NULL so the DMA request would never start.
