2008-11-12Fix possible null pointer dereference in info messageMauro Carvalho Chehab

2008-11-12Skip reading eeprom in newer Empia devicesMauro Carvalho Chehab
From: Devin Heitmueller <devin.heitmueller@gmail.com> Skip reading eeprom in newer Empia devices Empia switched to a 16-bit addressable eeprom in newer devices. While we could certainly write a routine to read the eeprom, there is nothing of use in there that cannot be accessed through registers, and there is the risk that we could corrupt the eeprom (since a 16-bit read call is interpreted as a write call by 8-bit eeproms). So just be safe and bail out of the function. Thanks for Ray Lu from Empia for providing the em2874 datasheet.

2008-11-09cx18: Fix unitialized variable problem upon APU firmware file read failureAndy Walls
From: Andy Walls <awalls@radix.net> If APU firmware file read failed, the jump vector to the APU was undefined and the APU would be started executing garbage.

2008-11-09cx18: Prevent CX23418 from clearing it's outgoing ack interrupts to driverAndy Walls
From: Andy Walls <awalls@radix.net> When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it also received that interrupt and cleared the flag before the linux driver could see what the interrupt was for. This fix prevents the CPU from receiving an IRQ for it's own outgoing ack's to the linux driver. This fix is critical now that the linux driver doesn't poll but relies on these ack interrupts.

2008-11-08uvcvideo: Handle failed video GET_{MIN|MAX|DEF} requests more gracefullyLaurent Pinchart
From: Laurent Pinchart <laurent.pinchart@skynet.be> Failed requests will now generate a one-time warning message instead of the usual "Failed to query..." error, which should be more user-friendly. The driver will also recover automatically from failed GET_MIN/GET_MAX requests when the device is half-broken without requiring the MINMAX quirk (fully broken devices still need the quirk).

2008-11-08uvcvideo: Sort the frame descriptors during parsingLaurent Pinchart
From: Laurent Pinchart <laurent.pinchart@skynet.be> The UVC specification does not require frame descriptors to be sorted by bFrameIndex. At least one camera (145f:013e) is known not to sort the descriptors properly, so they need to be sorted during parsing as the driver then accesses them by index.

From: Andy Walls <awalls@radix.net> cx18: Improve handling of outgoing mailboxes detected to be busy. When encountering a busy mailbox, sleep instead of polling, and wait for interrupt or timeout. If the mailbox is still busy, force it free. When sending commands, make sure we never create a situation where we mark the mailbox busy upon sending, and ensure we always have a method to cleanly recover from a busy mailbox.

In order to properly lock the epu2cpu mailbox for driver to CX23418 commands, the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ context to a work queue.
