Hi Kongyang,
`$ make bananapi_f3_defconfig && make` produces the following warning.
In file included from drivers/serial/ns16550.c:13: include/ns16550.h:205:9: warning: "UART_IIR_ID" redefined 205 | #define UART_IIR_ID 0x06 /* Mask for the interrupt ID */ | ^~~~~~~~~~~ In file included from include/configs/bananapi_f3.h:10, from include/config.h:3, from drivers/serial/ns16550.c:8: include/linux/serial_reg.h:33:9: note: this is the location of the previous definition 33 | #define UART_IIR_ID 0x0e /* Mask for the interrupt ID */ | ^~~~~~~~~~~
There seems to be Macro redefinition. Could you please take a look?
Best regards, Leo
