As reported by Trevor, doing several opening/streaming/closing operations to the demux causes it to fail. I was able to simulate this bug too. I also noticed that, sometimes, changing channels with au0828, the same thing happens. Most of the issues seem to be due to some hardware bug, that causes the device to not fill all the URBs allocated. When the bug happens, the only known fix is to either replug the device, or to send an USB reset to it. There's also a hack a the au0828 driver that starts a thread that tries to reset the device when a package doesn't start with a sync. One of the culpits for this bad hardware behavior seem to be caused by the lack of stopping and restarting the stream every time a new channel is set. This patch warrants that the stream will be properly reset every time the set_frontend callback is called, partially solving the problem. A complete fix, however, would also need to check the PM conditions for the tuner and demux. Reported-by:

If the tuner is already disconnected, It is meaningless to go on doing the stream-restart operation, It is better to cancel this operation. Signed-off-by:

The RC support o Nova-TD is broken, as the RC endpoint there is an interrupt endpoint. That produces an ugly calltrace at the Kernel logs: WARNING: CPU: 2 PID: 56 at drivers/usb/core/urb.c:450 usb_submit_urb+0x1fd/0x5c0() usb 1-1.2: BOGUS urb xfer, pipe 3 != type 1 Modules linked in: rc_dib0700_rc5(OF) dvb_usb_dib0700(OF) dib9000(OF) dib8000(OF) dib7000m(OF) dib0090(OF) dib0070(OF) dib7000p(OF) dib3000mc(OF) dibx000_common(OF) dvb_usb(OF) rc_core(OF) snd_usb_audio snd_usbmidi_lib snd_hwdep snd_rawmidi snd_seq snd_seq_device snd_pcm snd_timer snd soundcore bnep bluetooth 6lowpan_iphc rfkill au0828(OF) xc5000(OF) au8522_dig(OF) au8522_common(OF) tveeprom(OF) dvb_core(OF) nouveau i915 mxm_wmi ttm i2c_algo_bit drm_kms_helper drm r8169 mii i2c_core video wmi [last unloaded: au0828] CPU: 2 PID: 56 Comm: khubd Tainted: GF O 3.14.2-200.fc20.x86_64 #1 Hardware name: SAMSUNG ELECTRONICS CO., LTD. 550P5C/550P7C/SAMSUNG_NP1234567890, BIOS P05ABI.016.130917.dg 09/17/2013 0000000000000000 00000000610866bc ffff880223703860 ffffffff816eec92 ffff8802237038a8 ffff880223703898 ffffffff8108a1bd ffff8800916a2180 ffff8801d5b16000 0000000000000003 0000000000000003 0000000000000020 Call Trace: [<ffffffff816eec92>] dump_stack+0x45/0x56 [<ffffffff8108a1bd>] warn_slowpath_common+0x7d/0xa0 [<ffffffff8108a23c>] warn_slowpath_fmt+0x5c/0x80 [<ffffffff814e3ebd>] usb_submit_urb+0x1fd/0x5c0 [<ffffffffa0445925>] dib0700_rc_setup+0xb5/0x120 [dvb_usb_dib0700] [<ffffffffa0445a58>] dib0700_probe+0xc8/0x130 [dvb_usb_dib0700] ...

This patch remove variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Verified by compilation only.

The include/media/s5p_fimc.h header has been removed in commit 49b2f4c5 ("exynos4-is: Remove support for non-dt platforms"). This broke compilation of the m5mols driver. Include the include/media/exynos-fimc.h header instead, which contains the S5P_FIMC_TX_END_NOTIFY definition required by the driver. Signed-off-by:

Change the I/O endpoint handling of the mceusb driver to respect the endpoint type reported by device (bulk/interrupt), rather than treating all endpoints as type interrupt, which breaks devices using bulk endpoints when connected to a xhci controller. Accordingly, change the function calls to initialize an endpoint's transfer pipe and urb handlers to use the correct function based on the endpoint type.

Currently stk1160_read_reg() uses a stack-allocated char to get the read control value. This is wrong because usb_control_msg() requires a kmalloc-ed buffer. This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive the read value. While here, let's remove the urb_buf array which was meant for a similar purpose, but never really used.
