Use comedi_timeout() to wait for the analog input end-of-conversion. Since this is the sample skeleton driver, add comments about how the callback function works with comedi_timeout(). Signed-off-by:

H Hartley Sweeten authored
Introduce a comedi core helper function to handle the boilerplate needed by the drivers to busy- wait for a condition to occur. Typically this condition is the analog input/output end-of-conversion used with the comedi (*insn_read) and (*insn_write) operations. To use this function, the drivers just need to provide a callback that checks for the desired condition. The callback should return 0 if the condition is met or -EBUSY if it is still waiting. Any other errno will be returned to the caller. If the timeout occurs before the condition is met -ETIMEDOUT will be returned. The parameters to the callback function are the comedi_device, comedi_subdevice, and comedi_insn pointers that were passed to the (*insn_read) or (*insn_write) as well as an unsigned long, driver specific, 'context' that can be used to pass any other information that might be needed in the callback. This 'context' could be anything such as the register offset to read the status or the bits needed to check the status. The comedi_timeout() function itself does not use any of these parameters. This will help remove all the crazy "wait this many loops" used by some of the drivers. It also creates a common errno for comedi to detect when a timeout occurs. ADC/DAC conversion times are typically pretty fast, usually around 100K samples/sec (10 usec). A conservative timeout of 1 second is used in comedi_timeout(). Signed-off-by:

The rtw_recv_indicatepkt() function in the file named drivers/staging/rtl8188eu/os_dep/recv_linux.c has this strange code: rcu_read_lock(); rcu_dereference(padapter->pnetdev->rx_handler_data); rcu_read_unlock(); This code has no effect. Normally, you would assign the result of rcu_dereference() to some variable, but it is not clear from the code what variable that would be. Therefore, this patch applies to the TODO file instead of the code itself. Signed-off-by:

In this conditional statement, if (chan < 16), but the instruction passed in data[0] is INSN_CONFIG_DIO_QUERY, the function does not return early, but the else-branch does not get executed either. As a result, mask would be used uninitialized in the next line. We want comedi_dio_insn_config() to use a chan_mask based on the chanspec for the INSN_CONFIG_DIO_QUERY instruction, so mask should be initialized to 0. Then, if instead the instruction is INSN_CONFIG_DIO_{INPUT,OUTPUT}, we return an error if (chan < 16) as these are invalid instructions for ports 0 and 1, or update the mask otherwise, so all the io_bits are modified for port 2. This ensures that mask is always initialized by the time it is used. Signed-off-by:Chase Southwood <chase.southwood@yahoo.com> Reviewed-by:
