As spares can be added to the array before the reshape is started,
we need to find and count them when checking there are enough.
The array could have been degraded, so we need to check all devices,
no just those out side of the range of devices in the array before
the reshape.
So instead of checking the index, check the In_sync flag as that
reliably tells if the device is a spare or this purpose.

There are two consecutive 'if' statements.
if (mddev->delta_disks >= 0)
....
if (mddev->delta_disks > 0)
The code in the second is equally valid if delta_disks == 0, and these
two statements are the only place that 'added_devices' is used.
So make them a single if statement, make added_devices a local
variable, and re-indent it all.
No functional change.

If we try to update_raid_disks and it fails, we should put
'delta_disks' back to zero. This is important because some code,
such as slot_store, assumes that delta_disks has been validated.

This error is reported by cppcheck:

It looks like cppcheck is correct, so fix this. No test was run.

While unloading the driver, the ps_usecount is incremented
before configuring gpio registers in deinit_device.
But it is failed to restore the ps_usecount after that.
The problem is that the chip is forcibly moved to FULL SLEEP
by radio_disable when mac80211 is reporting as idle
though ps_usecount is not zero.
This patch retores ps_usecount properly and ensures that
the chip is always moved to full sleep only if ps usage
count is zero which also helps in debugging deadbeef on
multivif case. And also fixes the following warning.
ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef
ath: Could not stop RX, we could be confusing the DMA engine when we
start RX up

ata_pio_sectors() expects buffer for each sector to be contained in a
single page; otherwise, it ends up overrunning the first page. This
is achieved by setting queue DMA alignment. If sector_size is smaller
than PAGE_SIZE and all buffers are sector_size aligned, buffer for
each sector is always contained in a single page.
This wasn't applied to ATAPI devices but IDENTIFY_PACKET is executed
as ATA_PROT_PIO and thus uses ata_pio_sectors(). Newer versions of
udev issue IDENTIFY_PACKET with unaligned buffer triggering the
problem and causing oops.
This patch fixes the problem by setting sdev->sector_size to
ATA_SECT_SIZE on ATATPI devices and always setting DMA alignment to
sector_size. While at it, add a warning for the unlikely but still
possible scenario where sector_size is larger than PAGE_SIZE, in which
case the alignment wouldn't be enough.

(1b4b:9123).
However, that change inadvertently caused the legacy IDE interface of
the controller (with the same pci id) to become associated with the AHCI
driver as well, causing the driver to try to bring the interface up in

The Linux network stack expects all GSO SKBs to have ip_summed ==
CHECKSUM_PARTIAL (which implies that the frame contains a partial
checksum) and the Xen network ring protocol similarly expects an SKB
which has GSO set to also have NETRX_csum_blank (which also implies a
partial checksum).
However there have been cases of buggy guests which mark a frame as
GSO but do not set csum_blank. If we detect that we a receiving such a
frame (which manifests as ip_summed != PARTIAL && skb_is_gso) then
force the SKB to partial and recalculate the checksum, since we cannot
rely on the peer having done so if they have not set csum_blank.
Add an ethtool stat to track occurances of this event.
