From: Arnd Bergmann <[email protected]>
commit c2781e4d9bc6d925dfc1ff833dfdaf12b69679de upstream.
dma_addr_t and phys_addr_t are distinct types and must not be
mixed, as both the values and the size of the type may be
different depending on what the remote device uses.
In this driver the compiler warns when the two types are different:
drivers/remoteproc/mtk_scp.c: In function 'scp_map_memory_region':
drivers/remoteproc/mtk_scp.c:454:9: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]
454 | &scp->phys_addr, GFP_KERNEL);
| ^~~~~~~~~~~~~~~
| |
| phys_addr_t * {aka unsigned int *}
In file included from drivers/remoteproc/mtk_scp.c:7:
include/linux/dma-mapping.h:642:15: note: expected 'dma_addr_t *' {aka 'long long unsigned int *'} but argument is of type 'phys_addr_t *' {aka 'unsigned int *'}
642 | dma_addr_t *dma_handle, gfp_t gfp)
Change the phys_addr member to be typed and named according
to how it is allocated.

commit d0550cd20e52558ecf6847a0f96ebd5d944c17e4 upstream.
The controller always supports link recovery for device in SS and SSP.
Remove the speed limit check. Also, when the device is in RESUME or
RESET state, it means the controller received the resume/reset request.
The driver must send the link recovery to acknowledge the request. They
are valid states for the driver to send link recovery.

commit 7762902c89c4c78d32ec562f1ada44d02039104b upstream.
st_lsm6dsx suffers of a read misalignment on untagged FIFO when
all 3 supported sensors (accel, gyro and ext device) are running
at different ODRs (the use-case is reported in the LSM6DSM Application
Note at pag 100).
Fix the issue taking into account decimation factor reading the FIFO
pattern.

commit 6bdf8f3efe867c5893e27431a555e41f54ed7f9a upstream.
The addition of the support for reading the temperature of ATA drives as
per commit 5b46903d8bf3 ("hwmon: Driver for disk and solid state drives
with temperature sensors") lists in the respective Kconfig section the
name of the module to be optionally built as "satatemp".
However, building the kernel modules with "CONFIG_SENSORS_DRIVETEMP=m",
does not generate a file named "satatemp.ko".
Instead, the rest of the original commit uses the term "drivetemp" and
a file named "drivetemp.ko" ends up in the kernel's modules directory.
This file has the right ingredients:
$ strings /path/to/drivetemp.ko | grep ^description
description=Hard drive temperature monitor
and modprobing it produces the expected result:
# drivetemp is not loaded
$ sensors -u drivetemp-scsi-4-0
Specified sensor(s) not found!
$ sudo modprobe drivetemp
$ sensors -u drivetemp-scsi-4-0
drivetemp-scsi-4-0
Adapter: SCSI adapter
temp1:
temp1_input: 35.000
temp1_max: 60.000
temp1_min: 0.000
temp1_crit: 70.000
temp1_lcrit: -40.000
temp1_lowest: 20.000
temp1_highest: 36.000
Fix Kconfig by referring to the true name of the module.

commit ec21bdc6dd16d74b3674ef1fd12ae8e4e7418603 upstream.
Commit 450312b640f9 ("ASoC: soc-core: remove DAI suspend/resume")
removed the DAI side suspend/resume hooks and switched entirely to
component suspend/resume. However the Samsung SoC s3c-i2s-v2 driver was
not updated.
Move the suspend/resume hooks from s3c-i2s-v2.c to s3c2412-i2s.c while
changing dai to component which allows to keep the struct
snd_soc_component_driver const.
This fixes build errors:

commit e7e0004abdd6f83ae4be5613b29ed396beff576c upstream.
XSK wakeup function triggers NAPI by posting a NOP WQE to a special XSK
ICOSQ. When the application floods the driver with wakeup requests by
calling sendto() in a certain pattern that ends up in mlx5e_trigger_irq,
the XSK ICOSQ may overflow.
Multiple NOPs are not required and won't accelerate the process, so
avoid posting a second NOP if there is one already on the way. This way
we also avoid increasing the queue size (which might not help anyway).

commit 9df8ba7c63073508e5aa677dade48fcab6a6773e upstream.
If probe fails after enabling the regulators regulator_put is called for
each supply without having them disabled before. This produces some
warnings like

commit 1e060a453c8604311fb45ae2f84f67ed673329b4 upstream.
After suspend & resume, wm8960_hw_params may be called when
bias_level is not SND_SOC_BIAS_ON, then wm8960_configure_clocking
is not called. But if sample rate is changed at that time, then
the output clock rate will be not correct.
So judgement of bias_level is SND_SOC_BIAS_ON in wm8960_hw_params
is not necessary and it causes above issue.

commit e1e8399eee72e9d5246d4d1bcacd793debe34dd3 upstream.
New struct nfsd4_blocked_lock allocated in find_or_allocate_block()
does not initialized nbl_list and nbl_lru.
If conflock allocation fails rollback can call list_del_init()
access uninitialized fields and corrupt memory.
v2: just initialize nbl_list and nbl_lru right after nbl allocation.
