+
+Device drivers should not mess with the DMA mask directly,
+but instead call dma_set_mask() etc if needed.
+
+In case of the mtk_eth_soc driver, the mask already gets set
+correctly when the device is created, and setting it again
+is against the documented API.
+
+This removes the incorrect setting.

+Subject: [PATCH 56/66] net: mediatek: check device_reset return code
+
+The device_reset() function may fail, so we have to check
+its return value, e.g. to make deferred probing work correctly.
+gcc warns about it because of the warn_unused_result attribute:
+
+drivers/net/ethernet/mediatek/mtk_eth_soc.c: In function 'mtk_probe':
+drivers/net/ethernet/mediatek/mtk_eth_soc.c:1679:2: error: ignoring return value of 'device_reset', declared with attribute warn_unused_result [-Werror=unused-result]
+
+This adds the trivial error check to propagate the return value
+to the generic platform device probe code.

+Subject: [PATCH 59/66] mtd: nand: add an mtd_to_nand() helper
+
+Some drivers are retrieving the nand_chip pointer using the container_of
+macro on a struct wrapping both the nand_chip and the mtd_info struct while
+the standard way of retrieving this pointer is through mtd->priv.
+Provide an helper to do that.

+
+Currently all NAND controller drivers are providing both the mtd_info and
+nand_chip struct and then let the NAND subsystem to initialize a few
+things before registering the mtd instance to the MTD layer.
+Embed an mtd_info field into nand_chip to add some consistency to all NAND
+controller drivers.
+This change will also help factorizing boilerplate code copied in all NAND
+drivers.

+Subject: [PATCH 66/66] net-next: mediatek: mtk_cal_txd_req() returns bad
+ value
+
+The code used to also support the PDMA engine, which had 2 packet pointers
+per descriptor. Because of this we have to divide the result by 2 and round
+it up. This is no longer needed as the code only supports QDMA.
