For this you can check the 'is_new' flag of +each control. For example, in the case of a volume/mute cluster the 'is_new' +flag of the mute control would be set if the user called VIDIOC_S_CTRL for +mute only. If the user would call VIDIOC_S_EXT_CTRLS for both mute and volume +controls, then the 'is_new' flag would be 1 for both controls. + +The 'is_new' flag is always 1 when called from v4l2_ctrl_handler_setup(). + VIDIOC_LOG_STATUS Support ========================= diff --git a/MAINTAINERS b/MAINTAINERS index 1af022e63668..9d12977b6baf 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -162,7 +162,7 @@ L: linux-serial@vger.kernel.org W: http://serial.sourceforge.net S: Maintained T: git git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6.git -F: drivers/serial/8250* +F: drivers/tty/serial/8250* F: include/linux/serial_8250.h 8390 NETWORK DRIVERS [WD80x3/SMC-ELITE, SMC-ULTRA, NE2000, 3C503, etc.] @@ -624,11 +624,15 @@ M: Lennert Buytenhek <kernel@wantstofly.org> L: linux-arm-kernel@lists.infradead.org (moderated for non-subscribers) S: Maintained -ARM/ATMEL AT91RM9200 ARM ARCHITECTURE +ARM/ATMEL AT91RM9200 AND AT91SAM ARM ARCHITECTURES M: Andrew Victor <linux@maxim.org.za> +M: Nicolas Ferre <nicolas.ferre@atmel.com> +M: Jean-Christophe Plagniol-Villard <plagnioj@jcrosoft.com> L: linux-arm-kernel@lists.infradead.org (moderated for non-subscribers) W: http://maxim.org.za/at91_26.html -S: Maintained +W: http://www.linux4sam.org +S: Supported +F: arch/arm/mach-at91/ ARM/BCMRING ARM ARCHITECTURE M: Jiandong Zheng <jdzheng@broadcom.com> @@ -888,8 +892,8 @@ F: arch/arm/mach-msm/ F: drivers/video/msm/ F: drivers/mmc/host/msm_sdcc.c F: drivers/mmc/host/msm_sdcc.h -F: drivers/serial/msm_serial.h -F: drivers/serial/msm_serial.c +F: drivers/tty/serial/msm_serial.h +F: drivers/tty/serial/msm_serial.c T: git git://codeaurora.org/quic/kernel/davidb/linux-msm.git S: Maintained @@ -1256,7 +1260,7 @@ F: drivers/mmc/host/atmel-mci-regs.h ATMEL AT91 / AT32 SERIAL DRIVER M: Nicolas Ferre <nicolas.ferre@atmel.com> S: Supported -F: drivers/serial/atmel_serial.c +F: drivers/tty/serial/atmel_serial.c ATMEL LCDFB DRIVER M: Nicolas Ferre <nicolas.ferre@atmel.com> @@ -1412,7 +1416,7 @@ M: Sonic Zhang <sonic.zhang@analog.com> L: uclinux-dist-devel@blackfin.uclinux.org W: http://blackfin.uclinux.org S: Supported -F: drivers/serial/bfin_5xx.c +F: drivers/tty/serial/bfin_5xx.c BLACKFIN WATCHDOG DRIVER M: Mike Frysinger <vapier.adi@gmail.com> @@ -1877,7 +1881,7 @@ L: linux-cris-kernel@axis.com W: http://developer.axis.com S: Maintained F: arch/cris/ -F: drivers/serial/crisv10.* +F: drivers/tty/serial/crisv10.* CRYPTO API M: Herbert Xu <herbert@gondor.apana.org.au> @@ -2216,7 +2220,7 @@ F: drivers/net/wan/dscc4.c DZ DECSTATION DZ11 SERIAL DRIVER M: "Maciej W.
