In drivers/media/dvb/siano/smsusb.c we have this code: ... kfree(dev); sms_info("device %p destroyed", dev); ... at least one static analysis tool (Coverity Prevent) complains about this as a use-after-free bug. While it's true that we do use the pointer variable after freeing it, the only use is to print the value of the pointer, so there's not actually any problem here. But still, silencing the complaint is trivial by just moving the kfree() call below the sms_info(), so why not just do it?. It doesn't change the workings of the code in any way, but it makes the tool shut up. The patch below also removes a rather pointless blank line.

On some situations, it is desired to use eeprom data to detect the board type. This patch adds a logic for it and fixes 2 detection issues: 1) 10Moons UT-821 uses a generic Trident ID. Other boards also share the same ID. So, better to use an alternative way for it; 2) Sometimes, HVR-900H is loaded with the default Trident ID. This seems to be some hardware bug or race condition. The new logic will only be enabled if the device is detected as having a generic ID. Signed-off-by: -

Avoid unnecessary DVB TS 188 sized packet copying from DMA buffer into stack. Backtrack one 188 sized packet just after some garbage bytes when possible. This obsoletes patch https://patchwork.kernel.org/patch/118147/Signed-off-by:

We leak the memory allocated to 'fw' (the firmware) when the variable goes out of scope. Fix the leak by calling release_firmware(fw) before 'fw' goes out of scope. Signed-off-by:

Register 42 bits 2,3,6 and 7 should be set to 0. This gives difficult locking on some channels and may be compensated for by other methods. This affects any driver using the stv0288 frontend on the default or earda inittab. Signed-off-by:

stv0288 Register 42 bits 6 & 7 should be set to 0. This is causing intermittent lock, the dvb-usb-lmedm04 driver uses register 50 (auto fine mode) to correct for this, this register is now returned to its default setting. Signed-off-by:

The ability to force the encoder or decoder chip was broken by commit 0ab6e1c3 in February 2009. As nobody complained for over 2 years, I take it that these parameters were no longer used so we can simply drop them. Signed-off-by:
