commit fe413a074a93d56f89e322c786aad8639afe76b4 upstream.
Remove call_usermodehelper starting /etc/acpi/events/RadioPower.sh that
is not available. This script is not part of the kernel and it is not
officially available on the www. The result is that this lines are just
dead code.

commit 2efb6edd52dc50273f5e68ad863dd1b1fb2f2d1c upstream.
(Actually, this is fixing the "Read the Current Status" command sent to
the device's outgoing mailbox, but it is only currently used for the PWM
instructions.)
The PCI-1760 is operated mostly by sending commands to a set of Outgoing
Mailbox registers, waiting for the command to complete, and reading the
result from the Incoming Mailbox registers. One of these commands is
the "Read the Current Status" command. The number of this command is
0x07 (see the User's Manual for the PCI-1760 at
<https://advdownload.advantech.com/productfile/Downloadfile2/1-11P6653/PCI-1760.pdf>.
The `PCI1760_CMD_GET_STATUS` macro defined in the driver should expand
to this command number 0x07, but unfortunately it currently expands to
0x03. (Command number 0x03 is not defined in the User's Manual.)
Correct the definition of the `PCI1760_CMD_GET_STATUS` macro to fix it.
This is used by all the PWM subdevice related instructions handled by
`pci1760_pwm_insn_config()` which are probably all broken. The effect
of sending the undefined command number 0x03 is not known.

commit 0fc801f8018000c8e64a275a20cb1da7c54e46df upstream.
This patch fixes a segfault by adding a null check on synth in
speakup_con_update(). The segfault can be reproduced as follows:
- Login into a text console
- Load speakup and speakup_soft modules
- Remove speakup_soft
- Switch to a graphics console
This is caused by lack of a null check on `synth` in
speakup_con_update().
Here's the sequence that causes the segfault:
- When we remove the speakup_soft, synth_release() sets the synth
to null.
- After that, when we change the virtual console to graphics
console, vt_notifier_call() is fired, which then calls
speakup_con_update().
- Inside speakup_con_update() there's no null check on synth,
so it calls synth_printf().
- Inside synth_printf(), synth_buffer_add() and synth_start(),
both access synth, when it is null and causing a segfault.
Therefore adding a null check on synth solves the issue.

In rtw_init_cmd_priv(), if `pcmdpriv->rsp_allocated_buf` is allocated
in failure, then `pcmdpriv->cmd_allocated_buf` will be not properly
released. Besides, considering there are only two error paths and the
first one can directly return, so we do not need implicitly jump to the
`exit` tag to execute the error handler.
So this patch added `kfree(pcmdpriv->cmd_allocated_buf);` on the error
path to release the resource and simplified the return logic of
rtw_init_cmd_priv(). As there is no proper device to test with, no runtime
testing was performed.

In some initialization functions of this driver, memory is allocated with
'i' acting as an index variable and increasing from 0. The commit in
"Fixes" introduces some clean-up codes in case of allocation failure,
which free memory in reverse order with 'i' decreasing to 0. However,
there are some problems:
- The case i=0 is left out. Thus memory is leaked.
- In case memory allocation fails right from the start, the memory
freeing loops will start with i=-1 and invalid memory locations will
be accessed.
One of these loops has been fixed in commit c8ff91535880 ("staging:
vt6655: fix potential memory leak"). Fix the remaining erroneous loops.

There are sleep in atomic context bugs when dm_fsync_timer_callback is
executing. The root cause is that the memory allocation functions with
GFP_KERNEL or GFP_NOIO parameters are called in dm_fsync_timer_callback
which is a timer handler. The call paths that could trigger bugs are
shown below:
(interrupt context)
dm_fsync_timer_callback
write_nic_byte
kzalloc(sizeof(data), GFP_KERNEL); //may sleep
usb_control_msg
kmalloc(.., GFP_NOIO); //may sleep
write_nic_dword
kzalloc(sizeof(data), GFP_KERNEL); //may sleep
usb_control_msg
kmalloc(.., GFP_NOIO); //may sleep
This patch uses delayed work to replace timer and moves the operations
that may sleep into the delayed work in order to mitigate bugs.

[ Upstream commit 89d78e0133e71ba324fb67ca776223fba4353418 ]
The Hantro H1 hardware can crop off pixels from the right and bottom of
the source frame. These are controlled with the H1_REG_IN_IMG_CTRL_OVRFLB
and H1_REG_IN_IMG_CTRL_OVRFLR in the H1_REG_IN_IMG_CTRL register.
The ChromeOS kernel driver that this was based on incorrectly added the
_D4 suffix H1_REG_IN_IMG_CTRL_OVRFLB. This field crops the bottom of the
input frame, and the number is _not_ divided by 4. [1]
Correct the name to avoid confusion when crop support with the selection
API is added.

[ Upstream commit 2e81948177d769106754085c3e03534e6cc1f623 ]
As the possible alloc failure of devm_kcalloc(), it could return null
pointer.
Therefore, 'strings' should be checked and return NULL if alloc fails to
prevent the dereference of the NULL pointer.
Also, the caller should also deal with the return value of the
gb_generate_enum_strings() and return -ENOMEM if returns NULL.
Moreover, because the memory allocated with devm_kzalloc() will be
freed automatically when the last reference to the device is dropped,
the 'gbe' in gbaudio_tplg_create_enum_kctl() and
gbaudio_tplg_create_enum_ctl() do not need to free manually.
But the 'control' in gbaudio_tplg_create_widget() and
gbaudio_tplg_process_kcontrols() has a specially error handle to
cleanup.
So it should be better to cleanup 'control' when fails.

commit 502408a61f4b7eb4713f44bd77f4a48e6cb1b59a upstream.
A new warning in clang points out a place in this file where a bitwise
OR is being used with boolean expressions:
In file included from drivers/staging/wlan-ng/prism2usb.c:2:
drivers/staging/wlan-ng/hfa384x_usb.c:3787:7: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical]

~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/staging/wlan-ng/hfa384x_usb.c:3787:7: note: cast one or both operands to int to silence this warning
1 warning generated.
The comment explains that short circuiting here is undesirable, as the
calls to test_and_{clear,set}_bit() need to happen for both sides of the
expression.
Clang's suggestion would work to silence the warning but the readability
of the expression would suffer even more. To clean up the warning and
make the block more readable, use a variable for each side of the
bitwise expression.

commit a44f9d6f9dc1fb314a3f1ed2dcd4fbbcc3d9f892 upstream.
There is a wrong comparison of the total size of the loaded firmware
css->fw->size with the size of a pointer to struct imgu_fw_header.
Turn binary_header into a flexible-array member[1][2], use the
struct_size() helper and fix the wrong size comparison. Notice
that the loaded firmware needs to contain at least one 'struct
imgu_fw_info' item in the binary_header[] array.
It's also worth mentioning that
"css->fw->size < struct_size(css->fwp, binary_header, 1)"
with binary_header declared as a flexible-array member is equivalent
to
"css->fw->size < sizeof(struct imgu_fw_header)"
with binary_header declared as a one-element array (as in the original
code).
The replacement of the one-element array with a flexible-array member
also helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().
