From: Mauro Carvalho Chehab Date: Tue, 2 Oct 2012 19:02:57 +0000 (-0300) Subject: em28xx: regression fix: use DRX-K sync firmware requests on em28xx X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2425bb3d4016ed95ce83a90b53bd92c7f31091e4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git em28xx: regression fix: use DRX-K sync firmware requests on em28xx 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 Cc: stable@kernel.org # for Kernel 3.6 - please note that driver location has changed Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/usb/em28xx/em28xx-dvb.c b/drivers/media/usb/em28xx/em28xx-dvb.c index 1662b70435b3..913e5227897a 100644 --- a/drivers/media/usb/em28xx/em28xx-dvb.c +++ b/drivers/media/usb/em28xx/em28xx-dvb.c @@ -318,6 +318,7 @@ static struct drxk_config terratec_h5_drxk = { .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 = { @@ -327,6 +328,7 @@ static struct drxk_config hauppauge_930c_drxk = { .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 = { @@ -340,12 +342,14 @@ struct drxk_config terratec_htc_stick_drxk = { .antenna_dvbt = true, /* The windows driver uses the same.
