f10f9fb216
This patch fixes the following sparse warnings. One is fixed by casting return value to a return type of the function. The others by creating a specific stmmac_platform.h which provides the bits related to the platform driver. drivers/net/ethernet/stmicro/stmmac/dwmac-meson.c:59:29: warning: incorrect type in return expression (different address spaces) drivers/net/ethernet/stmicro/stmmac/dwmac-meson.c:59:29: expected void * drivers/net/ethernet/stmicro/stmmac/dwmac-meson.c:59:29: got void [noderef] <asn:2>*reg drivers/net/ethernet/stmicro/stmmac/dwmac-meson.c:64:29: warning: symbol 'meson6_dwmac_data' was not declared.
