Hi,
I was playing with sparse and it flagged that in drivers/serial/8250.c
there is a duplicate initialiser in the uart_config[] array
(from Linus's git):
[PORT_NS16550A] = {
.name = "NS16550A",
.fifo_size = 16,
.tx_loadsz = 16,
.fcr = UART_FCR_ENABLE_FIFO | UART_FCR_R_TRIG_10,
.flags = UART_CAP_FIFO | UART_NATSEMI,
},
and
[PORT_U6_16550A] = {
.name = "U6_16550A",
.fifo_size = 64,
.tx_loadsz = 64,
.fcr = UART_FCR_ENABLE_FIFO | UART_FCR_R_TRIG_10,
.flags = UART_CAP_FIFO | UART_CAP_AFE,
},
now PORT_NS16550A is defined as 14 in serial_core.h:
#define PORT_NS16550A 14
and PORT_U6_16550A is defined as 14 in serial.h:
235dae5d (Philippe Langlais 2010-07-29 17:13:57 +0200 80) #define PORT_U6_16550A 14
I guess that might subtly break NS16550A users?
My assumption is that Philippe's addition should actually
be to the serial_core.h list which currently goes upto 18.
However, that leaves the question of why is there a set of nearly
but not quite idential defines in serial.h and serial_core.h?
(please leave me on cc for replies)
