One-element and zero-length arrays are deprecated. So, replace one-element array in struct fc_rscn_pl_s with flexible-array member. This results in no differences in binary output. Link: https://github.com/KSPP/linux/issues/339Signed-off-by:

I have an Iomega Z100P2 zip drive, but it does not work with my StarTech PEX1P2 AX99100 PCIe parallel port, which evidently does not support 16-bit or 32-bit EPP. Currently the only way to tell the PPA driver to use 8-bit EPP is to write 'mode=3' to /proc/scsi/ppa/*, but the driver doesn't actually distinguish between the three EPP modes and still tries to use 16-bit or 32-bit EPP. And even if writing to that file did make the driver use 8-bit EPP, it still wouldn't do me any good because by the time that file exists, the drive has already failed to initialize. Add a new parameter /sys/module/ppa/mode to set the transfer mode before initializing the drive. This parameter replaces the use of CONFIG_SCSI_IZIP_EPP16 in the PPA driver. At the same time, default to 8-bit EPP. 16-bit and 32-bit EPP are not necessary for the drive to function, nor are they part of the IEEE 1284 standard, so the driver should not assume that they are available.

To ensure that the PCI based QEMU UFS device properly works with Linux, register the device ID (0x0013) and vendor ID (0x1b36) of QEMU UFS device. QEMU UFS will enable testing of the UFS driver inside a virtual machine on systems without UFS host controller. It can also be used to preemptively implement and test new features before the real device is created.

When a timestamp update or an event acknowledgment command times out, the driver invokes the soft reset handler to recover the controller while holding a mutex lock. The soft reset handler also tries to acquire the same mutex to send initialization commands to the controller which leads to a deadlock scenario. To resolve the issue the driver will check thestatus and if this indicates the controller is operational, the driver will issue a diagnostic fault reset and exit out of the command processing function. If the controller is already faulted or asynchronously reset, then the driver will just exit the command processing function. Signed-off-by:

Only nodes whose state is at least past a PLOGI issue and strictly less than a PRLI issue should be put into device recovery mode upon RSCN receipt. Previously, the allowance of LOGO and PRLI completion states did not make sense because those nodes should be allowed to flow through and marked as NPort dissappeared as is normally done. A follow up RSCN GID_FT would recover those nodes in such cases. Signed-off-by:
