From e2adbecf72d54515b66f8631813ec49069669d5e Mon Sep 17 00:00:00 2001 From: Aapo Tahkola Date: Thu, 28 Sep 2006 00:47:51 -0300 Subject: [PATCH] V4L/DVB (5130): M920x: misc updates and fixes - hardware pid filtering no longer enabled unless in usb 1.x mode - more responsive rc handling - some minor bug fixes and code refolding - m9206_write delay dropped (doesn't seem to be needed) Signed-off-by: Aapo Tahkola Signed-off-by: Michael Krufky Signed-off-by: Mauro Carvalho Chehab --- drivers/media/dvb/dvb-usb/m920x.c | 213 ++++++++++++++++----------- drivers/media/dvb/dvb-usb/m920x.h | 18 +++ drivers/media/dvb/frontends/qt1010.h | 7 +- 3 files changed, 145 insertions(+), 93 deletions(-) diff --git a/drivers/media/dvb/dvb-usb/m920x.c b/drivers/media/dvb/dvb-usb/m920x.c index 292805aad6..197bc29bcb 100644 --- a/drivers/media/dvb/dvb-usb/m920x.c +++ b/drivers/media/dvb/dvb-usb/m920x.c @@ -62,23 +62,36 @@ static inline int m9206_write(struct usb_device *udev, u8 request, u16 value, u1 ret = usb_control_msg(udev, usb_sndctrlpipe(udev, 0), request, USB_TYPE_VENDOR | USB_DIR_OUT, value, index, NULL, 0, 2000);
