scsi: bfa: Increase requested firmware version to 3.2.5.1

2017-08-07T01:59:50+00:00

[ Upstream commit 2d1148f0f45079d25a0fa0d67e4fdb2a656d12fb ]

bna & bfa firmware version 3.2.5.1 was submitted to linux-firmware on
Feb 17 19:10:20 2015 -0500 in 0ab54ff1dc ("linux-firmware: Add QLogic BR
Series Adapter Firmware").

bna was updated to use the newer firmware on Feb 19 16:02:32 2015 -0500 in
3f307c3d70 ("bna: Update the Driver and Firmware Version")

bfa was not updated. I presume this was an oversight but it broke support
for bfa+bna cards such as the following
	04:00.0 Fibre Channel [0c04]: Brocade Communications Systems, Inc.
		1010/1020/1007/1741 10Gbps CNA [1657:0014] (rev 01)
	04:00.1 Fibre Channel [0c04]: Brocade Communications Systems, Inc.
		1010/1020/1007/1741 10Gbps CNA [1657:0014] (rev 01)
	04:00.2 Ethernet controller [0200]: Brocade Communications Systems,
		Inc. 1010/1020/1007/1741 10Gbps CNA [1657:0014] (rev 01)
	04:00.3 Ethernet controller [0200]: Brocade Communications Systems,
		Inc. 1010/1020/1007/1741 10Gbps CNA [1657:0014] (rev 01)

Currently, if the bfa module is loaded first, bna fails to probe the
respective devices with
[  215.026787] bna: QLogic BR-series 10G Ethernet driver - version: 3.2.25.1
[  215.043707] bna 0000:04:00.2: bar0 mapped to ffffc90001fc0000, len 262144
[  215.060656] bna 0000:04:00.2: initialization failed err=1
[  215.073893] bna 0000:04:00.3: bar0 mapped to ffffc90002040000, len 262144
[  215.090644] bna 0000:04:00.3: initialization failed err=1

Whereas if bna is loaded first, bfa fails with
[  249.592109] QLogic BR-series BFA FC/FCOE SCSI driver - version: 3.2.25.0
[  249.610738] bfa 0000:04:00.0: Running firmware version is incompatible with the driver version
[  249.833513] bfa 0000:04:00.0: bfa init failed
[  249.833919] scsi host6: QLogic BR-series FC/FCOE Adapter, hwpath: 0000:04:00.0 driver: 3.2.25.0
[  249.841446] bfa 0000:04:00.1: Running firmware version is incompatible with the driver version
[  250.045449] bfa 0000:04:00.1: bfa init failed
[  250.045962] scsi host7: QLogic BR-series FC/FCOE Adapter, hwpath: 0000:04:00.1 driver: 3.2.25.0

Increase bfa's requested firmware version. Also increase the driver
version.  I only tested that all of the devices probe without error.

scsi: snic: Return error code on memory allocation failure

2017-08-07T01:59:49+00:00

[ Upstream commit 0371adcdaca92912baaa3256ed13e058a016e62d ]

If a call to mempool_create_slab_pool() in snic_probe() returns NULL,
return -ENOMEM to indicate failure. mempool_creat_slab_pool() only fails
if it cannot allocate memory.

HID: ignore Petzl USB headlamp

This headlamp contains a dummy HID descriptor which pretends to be
a mouse-like device, but can't be used as a mouse at all.

sh_eth: enable RX descriptor word 0 shift on SH7734

[ Upstream commit 71eae1ca77fd6be218d8a952d97bba827e56516d ]

The RX descriptor word 0 on SH7734 has the RFS[9:0] field in bits 16-25
(bits  0-15 usually used for that are occupied by the packet checksum).
Thus  we need to set the 'shift_rd0'  field in the SH7734 SoC data...

net: usb: asix_devices: add .reset_resume for USB PM

2017-08-07T01:59:48+00:00

[ Upstream commit 63dfb0dac9055145db85ce764355aef2f563739a ]

The USB core may call reset_resume when it fails to resume asix device.
And USB core can recovery this abnormal resume at low level driver,
the same .resume at asix driver can work too. Add .reset_resume can
avoid disconnecting after backing from system resume, and NFS can
still be mounted after this commit.

nvmem: imx-ocotp: Fix wrong register size

2017-08-07T01:59:48+00:00

[ Upstream commit 14ba972842f9e84e6d3264bc0302101b8a792288 ]

All i.MX6 SoCs have an OCOTP Controller with 4kbit fuses. The i.MX6SL is
an exception and has only 2kbit fuses.

In the TRM for the i.MX6DQ (IMX6QDRM - Rev 2, 06/2014) the fuses size is
described in chapter 46.1.1 with:
"32-bit word restricted program and read to 4Kbits of eFuse OTP(512x8)."

In the TRM for the i.MX6SL (IMX6SLRM - Rev 2, 06/2015) the fuses size is
described in chapter 34.1.1 with:
"32-bit word restricted program and read to 2 kbit of eFuse OTP(128x8)."

Since the Freescale Linux kernel OCOTP driver works with a fuses size of
2 kbit for the i.MX6SL, it looks like the TRM is wrong and the formula
to calculate the correct fuses size has to be 256x8.

Xen: ARM: Zero reserved fields of xatp before making hypervisor call

[ Upstream commit 0b47a6bd1150f4846b1d61925a4cc5a96593a541 ]

Ensure all reserved fields of xatp are zero before making
hypervisor call to XEN in xen_map_device_mmio().
xenmem_add_to_physmap_one() in XEN fails the mapping request if
extra.res reserved field in xatp is not zero for XENMAPSPACE_dev_mmio
