genwq: no need to check return value of debugfs_create functions When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

GenWQE: Support blocking when DDCB queue is busy When the GenWQE hardware queue was busy, the driver returned simply -EBUSY. This caused polling by applications which increased the load on the already busy system. This change implements the possiblity to sleep on a waitqueue instead when the DDCB queue is busy. The requestor is woken up when there is free space on the queue again. The old way to get -EBUSY is still available if the device is openend with O_NONBLOCKING. The default is now blocking behavior.

The information can be retrieved by using modinfo genwqe_card. modinfo genwqe_card will provide the same information.

GenWQE: Add support for EEH error recovery This patch implements the callbacks and functions necessary to have EEH recovery support. It adds a config option to enable or disable explicit calls to trigger platform specific mechanisms on error recovery paths. This option is enabled by default only on PPC64 systems and can be overritten via debugfs. If this option is enabled, on the error recovery path the driver will call pci_channel_offline() to check for error condition and issue non-raw MMIO reads to trigger early EEH detection in case of hardware failures. This is necessary since the driver MMIO helper funtions use raw accessors.

Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
