This patch simplifies alloc_tx_struct and alloc_rx_struct in gdm_sdio.c and gdm_usb.c by replacing kmalloc+memset with kzalloc and reorganizing the code. Signed-off-by:

The 8255 based boards in the ni_pcidio driver are all simple memory mapped 8255 boards that don't require the dma support provided by the mite driver. Move the support for these boards from the ni_pcidio driver to the generic 8255_pci driver. Signed-off-by:

Some of the PCI based 8255 boards that can be supported by this driver use memory mapped i/o. Add the code needed to support these boards. Signed-off-by:

This driver supports PCI boards from multiple vendors. It's possible for boards from different vendors to have the same device id. Add the vendor id to the boardinfo so pci_8255_find_boardinfo() matches the pci_dev to the correct boardinfo. Signed-off-by:

Due to the rename of this file, change all the adl_pci7296_* to pci_8255_* so that everything has namespace associated with this driver. Also, fix the comedi description comment based on the rename of the file. Remove the extra comment about the driver attach. Modify the PCI_DEVICE_ID_* defines in preparation of moving additional vendor/device ids into this driver. Signed-off-by:

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:

Jens Taprogge authored
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:

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:
