From 6400a8c5afb54a1018c4d01b7f1ad28c4e0ef659 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sat, 16 Jun 2012 16:02:57 -0300 Subject: [PATCH] [media] dvb_usb_v2: change USB stream config logic Initial / default USB stream configuration is now set always as a dvb_usb_device_properties. Dynamic configuration is done top of that if callback .get_usb_stream_config() exists. Default values are set when callback is called so callback needs only change values that are different than default. In addition of that define two macros DVB_USB_STREAM_BULK() and DVB_USB_STREAM_ISOC() for filling struct usb_data_stream_properties Signed-off-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab --- drivers/media/dvb/dvb-usb/dvb_usb_common.h | 2 +- drivers/media/dvb/dvb-usb/dvb_usb_dvb.c | 21 ++++++--------------- drivers/media/dvb/dvb-usb/usb_urb.c | 2 +- 3 files changed, 8 insertions(+), 17 deletions(-) diff --git a/drivers/media/dvb/dvb-usb/dvb_usb_common.h b/drivers/media/dvb/dvb-usb/dvb_usb_common.h index e1cff154c0ec..c94a900c3264 100644 --- a/drivers/media/dvb/dvb-usb/dvb_usb_common.h +++ b/drivers/media/dvb/dvb-usb/dvb_usb_common.h @@ -17,7 +17,7 @@ extern int dvb_usbv2_disable_rc_polling; extern int dvb_usbv2_device_power_ctrl(struct dvb_usb_device *d, int onoff); extern int usb_urb_initv2(struct usb_data_stream *stream, - struct usb_data_stream_properties *props); + const struct usb_data_stream_properties *props); extern int usb_urb_exitv2(struct usb_data_stream *stream); extern int usb_urb_submitv2(struct usb_data_stream *stream, struct usb_data_stream_properties *props); diff --git a/drivers/media/dvb/dvb-usb/dvb_usb_dvb.c b/drivers/media/dvb/dvb-usb/dvb_usb_dvb.c index 3cbae02ea51e..484114cbd0ba 100644 --- a/drivers/media/dvb/dvb-usb/dvb_usb_dvb.c +++ b/drivers/media/dvb/dvb-usb/dvb_usb_dvb.c @@ -34,31 +34,20 @@ static void dvb_usb_data_complete_raw(struct usb_data_stream *stream, int dvb_usbv2_adapter_stream_init(struct dvb_usb_adapter *adap) { - int ret; - struct usb_data_stream_properties stream_props; + pr_debug("%s: adap=%d\n", __func__, adap->id); adap->stream.udev = adap->dev->udev; adap->stream.user_priv = adap; - - /* resolve USB stream configuration for buffer alloc */ - if (adap->dev->props->get_usb_stream_config) { - ret = adap->dev->props->get_usb_stream_config(NULL, - &stream_props); - if (ret < 0) - return ret; - } else { - stream_props = adap->props->stream; - } - - /* FIXME: can be removed as set later in anyway */ adap->stream.complete = dvb_usb_data_complete; - return usb_urb_initv2(&adap->stream, &stream_props); + return usb_urb_initv2(&adap->stream, &adap->props->stream); } int dvb_usbv2_adapter_stream_exit(struct dvb_usb_adapter *adap) { + pr_debug("%s: adap=%d\n", __func__, adap->id); usb_urb_exitv2(&adap->stream); + return 0; } @@ -133,6 +122,8 @@ static int dvb_usb_ctrl_feed(struct dvb_demux_feed *dvbdmxfeed, int onoff) /* resolve USB stream configuration */ if (adap->dev->props->get_usb_stream_config) { + memcpy(&stream_props, &adap->props->stream, + sizeof(struct usb_data_stream_properties)); ret = adap->dev->props->get_usb_stream_config( adap->fe[adap->active_fe], &stream_props); diff --git a/drivers/media/dvb/dvb-usb/usb_urb.c b/drivers/media/dvb/dvb-usb/usb_urb.c index 16e9fa03c847..32e80be2168d 100644 --- a/drivers/media/dvb/dvb-usb/usb_urb.c +++ b/drivers/media/dvb/dvb-usb/usb_urb.c @@ -306,7 +306,7 @@ int usb_urb_reconfig(struct usb_data_stream *stream, } int usb_urb_initv2(struct usb_data_stream *stream, - struct usb_data_stream_properties *props) + const struct usb_data_stream_properties *props) { int ret; -- 2.34.1
