[SCSI] qla4xxx: Re-register IRQ handler while retrying initialize of adapter

Problem:
If initialization of adapter fails for some reason, then the interrupt handlers
are released. The interrupt handlers are not registered again when initialization
of adapter is retried.

Solution:
Re-register the interrupt handler when adapter initialization is retried.

to crash the system while there is SCSI activity and removing the device
have failed. Adding the device back again works as expected, with the

Issue:
Mailbox command timed out after switching from polling mode to interrupt mode.

Events:-
 1. Mailbox interrupts are disabled
 2. FW generates AEN and at same time driver enables Mailbox Interrupt
 3. Driver issues new mailbox to Firmware

In above case driver will not get AEN interrupts generated by FW in step #2 as
FW generated this AEN when interrupts are disabled. During the same time
driver enabled the mailbox interrupt, so driver will not poll for interrupt.
Driver will never process AENs generated in step #2 and issues new mailbox to
FW, but now FW is not able to post mailbox completion as AENs generated before
are not processed by driver.

Fix:
Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX.

Bjorn Helgaas [Tue, 6 Nov 2012 22:04:44 +0000 (15:04 -0700)]
[SCSI] gdth: Remove buggy ROM handling

The ROM address handling in gdth_init_pci() is useless and possibly
dangerous.  This patch removes it.

"pci_resource_start(pdev, 8)" is not well-defined.  PCI resources 0-5 are
standard PCI BARs and 6 is the expansion ROM.  Resource 8 is either an
SR-IOV BAR (if CONFIG_PCI_IOV=y, resources 7-12 are SR-IOV BARs) or a
bridge window (resources 7-10).

The GDT device is neither an SR-IOV device nor a bridge, so in either case
resource 8 should be zero since struct pci_dev is allocated with kzalloc().

It is illegal for a driver to write an arbitrary address to the ROM BAR
because it has no way of knowing whether the ROM will conflict with another
device.

I think the only effect of the code being removed was to:

  1) Enable the ROM at 0xFEFF0000 (possibly causing a conflict with
     another device)
  2) Delay one millisecond
  3) Write zero to the ROM BAR, disabling it

I doubt the delay is needed, but I left it since it seems innocuous.

dm9601: support dm9620 variant

dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum
offload, ..), but it can also be put in a dm9601 compatible mode, allowing

Ashish Jangam [Fri, 25 Jan 2013 08:33:49 +0000 (14:03 +0530)]
mfd: da9052/53 lockup fix

An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.

The failure case is where this unwanted write transfers incorrect data to
a critical register.

This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
will not affect the operation of the system.

btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the
first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/
btrfs_queue_worker for this inode, and then it locks the list, checks the
