As a side effect demods that detect the STOP bit for auto closing of the gate can be avoided, thereby a very minimal gain in disabling the auto detect feature as well.

One authored by Andy Burns and another authored by Suresh Siddha. Due to that, I'm applying the one that has less CodingStyle errors. I'm also adding both comments and the SOB's for both patches, since they are both interesting} Suresh Siddha commented: Alexey Fisher reported: > resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000 > 0xcfefffff PCI Bus 0000:01 BAR base is located in the middle of the 4K page and the hardcoded size argument makes the request span two pages causing the conflict. Fix the hard coded size argument in ioremap(). Andy Burns commented: I have already sent this patch on the linux-dvb list, but it didn't get much attention, so re-sending direct, I hope you all don't mind. While attempting to run mythtv in a xen domU, I encountered problems loading the driver for my saa7134 card, with an error from ioremap(). This error was due to the driver allocating an incorrectly sized mmio area, which was trapped by xen's permission checks, but this would go un-noticed on a kernel without xen. My card has a 1K sized mmio area, I've had information that other cards have 2K areas, perhaps others have different sizes, yet the driver always attempts to map 4K. I realise that the granularity of mapping is the page size, which typically would be 4K, but unless the card's base address happens to fall on a 4K boundary (mine does not) then the base+4K will end up spanning two pages, and this is when the error occurs under xen. My patch uses the pci_resource_len macro to determine the size required for the user's particular card, instead of the hardcoded 4K value. I've tested with a couple of printk() inside ioremap() that the start address and size do get rounded to the closest page boundary. With this patch I am able to successfully load the saa7134 driver and run mythtv under xen with my card, subject to correct pollirq settings in case of shared IRQ, I am still seeing occasional DMA panics, which I think are related to swiotlb handling by dom0/domU, usually the panic occurs when changing mux, once tuned to a mux, 12 hour continuous recordings are possible without errors.

When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with 2.6.24, I was met with an oops [1]. The problem is relevant to 2.6.25/26-rc also. dvb_frontend_init() was called either from re-creation of the kdvb-fe0 thread - seems unlikely, or someone called dvb_frontend_reinitialise(), causing this path in the thread - really unlikely, as I can't find any call-site for it. Either way, quite a number of drivers call dvb_usb_generic_rw() [2] without checking the validity of the relevant member in the dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw() sanity-check and fail (rather than loading from 0x120) seems reasonable defensive programming [3], in light of it being called in this way. The problem with this, is that drivers don't check the return code of the init call [4]. Does it make sense to cook a patch which allows the failure to be propagated back up, or am I missing something else?
