[PATCH 1/6] net: stmmac: return error if no DMA configuration is found

From: Niklas Cassel All drivers except pci glue layer calls stmmac_probe_config_dt. stmmac_probe_config_dt does a kzalloc dma_cfg. pci glue layer does kzalloc dma_cfg explicitly, so all current drivers does a kzalloc dma_cfg. Return an error if no DMA configuration is

[PATCH 3/3] pinctrl: sx150x: handle missing 'advanced' reg in sx1504 and sx1505

This fixes a problem where sx150x_regmap_reg_width() returns 8 for the data register (reg 0) for sx1504 where it should return 4, and return a correct 8 for sx1505 but for the wrong reason (both chips lack the 'advanced' register). This is not a real problem, since nothing depends on the function
