Note that the pacer does not have to be stopped when starting a new async command in pcl818_ai_cmd() or when the card is initialy reset by pcl818_reset(). The counters are all reset when the driver is initially attached and the counters used by the pacer are stopped when a command is canceled. Signed-off-by:

Add a new member to the comedi_device struct for a comedi_8254 'pacer'. This provides a convient place to store the data allocated by the comedi_8254 module for boards that use an 8254 device to create the data acquisition pacer clock. Automatically free this pointer in comedi_device_detach_cleanup() so that the drivers don't need to do it when then are detached. Signed-off-by:

A 8254 timer/counter is commonly used on data acquisition boards to provide the internal pacer clock used to acquire analog input samples. Some boards also to allow the timers to be used externally. Currently the 8254 timers are supported by comedi using the 8253.h header and a number of inline functions. This works for the internal pacer clock but requires the drivers to implement subdevice code necessary to use the timers externally. Introduce a new module to support both the internal pacer clock and the external counter subdevice. This will allow removing a bunch of duplicated code in the drivers and standardizes the comedi 8254 timer support. This implementation is based on the 8253.h inline functions and the various subdevice functionality in the comedi drivers. Signed-off-by:

The read/write of the PLX_INTRCS_REG during the driver detach is not necessary. The rtd_reset() function writes 0 to this register which will disable all interrupts. This also fixes a dereference after null check reported by coverity. Reported-by: coverity (CID 751066) Signed-off-by:

The {min,max}_scan_divisor values could overflow due to the unsigned int * insigned int calculation. Change the type of the local variable 'convert_divisor' to unsigned long long to avoid the possible overflow. Reported-by: coverity (CID 200653) Signed-off-by: -

The quick exit check of (mode == MODE_SINGLE_CHAN) results in coverity reporting a logically dead code issue in the switch code in labpc_ai_check_chanlist(). Remove the quick exit check and allow the function to handle the MODE_SINGLE_CHAN normally (the for loop will only happen 1 time and the function will return 0).

C99 says that a precision which is simply '.' with no following digits or * should be interpreted as 0, which means that these format strings actually mean 'print 16 spaces'. However, the kernel's printf implementation treats this case as if the precision was omitted. Don't rely on that quirk. Signed-off-by:
