Make use of dev_set_drvdata() and dev_get_drvdata() to store and obtain a pointer to the ipoctal struct corresponding to a struct dev. Previously we relied on a private list of devices. Signed-off-by:

Rename __tpci_request_irq() to tpci_enable_irq() and __tpci_free_irq() to tpci_disable_irq(). Change their second argument, move them above tpci200_interrupt(), and use tpci_disable_irq() in the latter Signed-off-by:

Minor cleanup. No functional changes. Signed-off-by:

Previously the return value from tpci200_interrupt was not quite correct if a slot had caused an interrupt but no handler was instellalled: IRQ_NONE was returned. However in this case we react to the interrupt by disabling the IPack device interrupt. Basically there are two cases the code now distinguishes: - The tpci200 has raised an interrupt. We handle it and return IRQ_HANDLED. - Our device did not raise an interrupt. We return IRQ_NONE. Signed-off-by:

Some of the device registers are accessed from both interrupt and non-interrupt context. To ensure proper read-modify-write modification of these registers we can not use the "global" tpci200 mutex. Instead a spin-lock is used. Signed-off-by:

In tpci200_request_irq as well as tpci200_free_irq we set and unset the pointer to struct slot_irq. This pointer is accessed in tpci200_interrupt. To ensure that the pointer is not freed after it has been fetched in tpci200_interrupt() it is now protected through RCU. Signed-off-by:

This way interrupt handling becomes independent of the channel number. Signed-off-by:

Each tty's driver_data is now pointing to the channel it is talking to. struct ipoctal_channel contains all the information the callbacks require to do their work. Signed-off-by:

By moving everything channel related into a separate struct we will be able to clean up a lot of code. In the end tty->driver_data will no longer need to point to ipoctal but instead can point to the respective channel. Signed-off-by:

It's possible to select video mode that exceeds the available video memory. This is potentially dangerous, fix by adding a check. The patch fixes system hangs seen occasionally when playing random videos with mplayer. Signed-off-by:

The legacy attach used the "dummy" boardinfo entry to allow matching a boardinfo to a pci card based on the "name" passed by the comedi core. This driver now uses the PCI auto config mechanism which always matches to the PCI vendor/device ids. Signed-off-by:

The 'valid' variable in the private data is only used in the detach of the board to determine if the pci1710_reset() function can be called. That function only requires a valid dev->iobase to work. Use that for the check instead and remove the unneeded variable from the private data. Signed-off-by:

Convert this PCI driver to use the comedi PCI auto config attach mechanism by adding an 'attach_pci' callback function. Since the driver does not require any external configuration options, and the legacy 'attach' callback is now optional, remove it. Signed-off-by:
