The qla2xxx driver had this issue as well when the newer array firmware
returned the retry_delay_timer in the fcp_rsp. The bnx2fc is not handling
the masking of the scope bits either so the retry_delay_timestamp value
lands up being a large value added to the timer timestamp delaying I/O for
up to 27 Minutes. This patch adds similar code to handle this to the
bnx2fc driver to avoid the huge delay.

When calling thermal_add_hwmon_sysfs(), the device type is sanitized by
replacing '-' with '_'. However tz->type remains unsanitized. Thus
calling thermal_hwmon_lookup_by_type() returns no device. And if there is
no device, thermal_remove_hwmon_sysfs() fails with "hwmon device lookup
failed!".
The result is unregisted hwmon devices in the sysfs.

Currently the suspend reg_field maps to the pmic voltage selection bits
and is used during suspend_enabe/disable() and during get_mode(). This
seems to be wrong for both use cases.
Use case one (suspend_enabe/disable):
Those callbacks are used to mark a regulator device as enabled/disabled
during suspend. Marking the regulator enabled during suspend is done by
the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers.
Setting this bit tells the DA9062 PMIC state machine to keep the
regulator on in POWERDOWN mode and switch to suspend voltage.
Use case two (get_mode):
The get_mode callback is used to retrieve the active mode state. Since
the regulator-setting-A is used for the active state and
regulator-setting-B for the suspend state there is no need to check
which regulator setting is active.

second parameter of ntb_peer_mw_get_addr is pointing to wrong memory
window index by passing "peer gidx" instead of "local gidx".
For ex, "local gidx" value is '0' and "peer gidx" value is '1', then
on peer side ntb_mw_set_trans() api is used as below with gidx pointing to
local side gidx which is '0', so memroy window '0' is chosen and XLAT '0'
will be programmed by peer side.
ntb_mw_set_trans(perf->ntb, peer->pidx, peer->gidx, peer->inbuf_xlat,
peer->inbuf_size);
Now, on local side ntb_peer_mw_get_addr() is been used as below with gidx
pointing to "peer gidx" which is '1', so pointing to memory window '1'
instead of memory window '0'.
ntb_peer_mw_get_addr(perf->ntb, peer->gidx, &phys_addr,

In case of WM1811 device there are currently being registered controls
referring to registers not existing on that device.
It has been noticed when getting values of "AIF1ADC2 Volume", "AIF1DAC2
Volume" controls was failing during ALSA state restoring at boot time:
"amixer: Mixer hw:0 load error: Device or resource busy"
Reading some registers through I2C was failing with EBUSY error and
indeed these registers were not available according to the datasheet.
To fix this controls not available on WM1811 are moved to a separate
array and registered only for WM8994 and WM8958.
There are some further differences between WM8994 and WM1811,
e.g. registers 603h, 604h, 605h, which are not covered in this patch.

User space programs like udevd may try to read to partitions at the
same time the driver detects a namespace is unusable, and may deadlock
if revalidate_disk() is called while such a process is waiting to
enter the frozen queue. On detecting a dead namespace, move the disk
revalidate after unblocking dispatchers that may be holding bd_butex.
