If anyone has any objections, please let me know. ------------------ From: Mauro Carvalho Chehab commit 2425bb3d4016ed95ce83a90b53bd92c7f31091e4 upstream. As em28xx-dvb will always be initialized asynchronously, there's no need anymore for a separate thread to load the DRX-K firmware. Fixes a known regression with kernel 3.6 with tda18271 driver and asynchronous DRX-K firmware load. Antti tested it with the following hardware: Hauppauge WinTV HVR 930C MaxMedia UB425-TC PCTV QuatroStick nano (520e) Tested-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman --- drivers/media/video/em28xx/em28xx-dvb.c | 5 +++++ 1 file changed, 5 insertions(+) --- a/drivers/media/video/em28xx/em28xx-dvb.c +++ b/drivers/media/video/em28xx/em28xx-dvb.c @@ -316,6 +316,7 @@ static struct drxk_config terratec_h5_dr .no_i2c_bridge = 1, .microcode_name = "dvb-usb-terratec-h5-drxk.fw", .qam_demod_parameter_count = 2, + .load_firmware_sync = true, }; static struct drxk_config hauppauge_930c_drxk = { @@ -325,6 +326,7 @@ static struct drxk_config hauppauge_930c .microcode_name = "dvb-usb-hauppauge-hvr930c-drxk.fw", .chunk_size = 56, .qam_demod_parameter_count = 2, + .load_firmware_sync = true, }; struct drxk_config terratec_htc_stick_drxk = { @@ -338,12 +340,14 @@ struct drxk_config terratec_htc_stick_dr .antenna_dvbt = true, /* The windows driver uses the same.
