The Kconfig symbol SERIAL_S3C2412 got removed in commit da121506eb03ee5daea55404709110b798bd61d9 ("serial: samsung: merge probe() function from all SoC specific extensions"). But it also added a last reference to that symbol. The commit and the tree make clear that CPU_S3C2412 should have been used instead. Signed-off-by: Paul Bolle <pebolle@xxxxxxxxxx> --- 0) The net effect of this is that the number of uarts of the S3C2412 CPU drops from 4 to 3. So this needs testing (by people with access to that hardware). 1) Related note: a few lines down there's the line default 4 if SERIAL_SAMSUNG_UARTS_4 || CPU_S3C2416 The "|| CPU_S3C2416" part looks superfluous. drivers/tty/serial/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/tty/serial/Kconfig b/drivers/tty/serial/Kconfig index 40ddbe4..7e7006f 100644 --- a/drivers/tty/serial/Kconfig +++ b/drivers/tty/serial/Kconfig @@ -211,7 +211,7 @@ config SERIAL_SAMSUNG config SERIAL_SAMSUNG_UARTS_4 bool depends on PLAT_SAMSUNG - default y if !(CPU_S3C2410 || SERIAL_S3C2412 || CPU_S3C2440 || CPU_S3C2442) + default y if !(CPU_S3C2410 || CPU_S3C2412 || CPU_S3C2440 || CPU_S3C2442) help Internal node for the common case of 4 Samsung compatible UARTs -- 1.7.11.7 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
