Got a bit paranoid after bad things happened with v2 and v3. ahaha... in this case it's fine. The whole patch was suggested by Krzysztof, so that it makes sense to add this tag. What Krzysztof complained about is that you accidentally added his r-b without him telling you explicitely. > > > >> --- > >> include/linux/serial_s3c.h | 12 ++++++------ > >> 1 file changed, 6 insertions(+), 6 deletions(-) > >> > >> diff --git a/include/linux/serial_s3c.h b/include/linux/serial_s3c.h > >> index 1672cf0810ef..1e8686695487 100644 > >> --- a/include/linux/serial_s3c.h > >> +++ b/include/linux/serial_s3c.h > >> @@ -249,9 +249,9 @@ > >> #define APPLE_S5L_UCON_RXTO_ENA 9 > >> #define APPLE_S5L_UCON_RXTHRESH_ENA 12 > >> #define APPLE_S5L_UCON_TXTHRESH_ENA 13 > >> -#define APPLE_S5L_UCON_RXTO_ENA_MSK (1 << APPLE_S5L_UCON_RXTO_ENA) > >> -#define APPLE_S5L_UCON_RXTHRESH_ENA_MSK (1 << APPLE_S5L_UCON_RXTHRESH_ENA) > >> -#define APPLE_S5L_UCON_TXTHRESH_ENA_MSK (1 << APPLE_S5L_UCON_TXTHRESH_ENA) > >> +#define APPLE_S5L_UCON_RXTO_ENA_MSK BIT(APPLE_S5L_UCON_RXTO_ENA) > >> +#define APPLE_S5L_UCON_RXTHRESH_ENA_MSK BIT(APPLE_S5L_UCON_RXTHRESH_ENA) > >> +#define APPLE_S5L_UCON_TXTHRESH_ENA_MSK BIT(APPLE_S5L_UCON_TXTHRESH_ENA) > >> > >> #define APPLE_S5L_UCON_DEFAULT (S3C2410_UCON_TXIRQMODE | \ > >> S3C2410_UCON_RXIRQMODE | \ > >> @@ -260,9 +260,9 @@ > >> APPLE_S5L_UCON_RXTHRESH_ENA_MSK | \ > >> APPLE_S5L_UCON_TXTHRESH_ENA_MSK) > >> > >> -#define APPLE_S5L_UTRSTAT_RXTHRESH (1<<4) > >> -#define APPLE_S5L_UTRSTAT_TXTHRESH (1<<5) > >> -#define APPLE_S5L_UTRSTAT_RXTO (1<<9) > >> +#define APPLE_S5L_UTRSTAT_RXTHRESH BIT(4) > >> +#define APPLE_S5L_UTRSTAT_TXTHRESH BIT(5) > >> +#define APPLE_S5L_UTRSTAT_RXTO BIT(9) > >> #define APPLE_S5L_UTRSTAT_ALL_FLAGS (0x3f0) > > > > You could make this GENMASK(0x3f, 4) > Good idea, given the above context I think I may add > > Suggested-by: Andi Shyti <andi.shyti@kernel.org> ehm... not in this case. Mine is a suggestion as reviewer and this little comment does not deserve a "Suggested-by" like in Krzysztof's case. > too. And actually it should be GENMASK(9, 3) You find out the right parameters :-) Thanks, Andi > > > > Andi > > Nick Chan >
