The mapping is incorrect for RGB565_1X16 as it should be

A problem about insmod megachips-stdpxxxx-ge-b850v3-fw.ko failed is
triggered with the following log given:
[ 4497.981497] Error: Driver 'stdp4028-ge-b850v3-fw' is already registered, aborting...
insmod: ERROR: could not insert module megachips-stdpxxxx-ge-b850v3-fw.ko: Device or resource busy
The reason is that stdpxxxx_ge_b850v3_init() returns i2c_add_driver()
directly without checking its return value, if i2c_add_driver() failed,
it returns without calling i2c_del_driver() on the previous i2c driver,
resulting the megachips-stdpxxxx-ge-b850v3-fw can never be installed
later.
A simple call graph is shown as below:
stdpxxxx_ge_b850v3_init()
i2c_add_driver(&stdp4028_ge_b850v3_fw_driver)
i2c_add_driver(&stdp2690_ge_b850v3_fw_driver)
i2c_register_driver()
driver_register()
bus_add_driver()
priv = kzalloc(...) # OOM happened
# return without delete stdp4028_ge_b850v3_fw_driver
Fix by calling i2c_del_driver() on stdp4028_ge_b850v3_fw_driver when
i2c_add_driver() returns error.

As of commit eae06120f1974e1a ("drm: refuse ADDFB2 ioctl for broken
bigendian drivers"), drivers must set the
quirk_addfb_prefer_host_byte_order quirk to make the drm_mode_addfb()
compat code work correctly on big-endian machines.
While that works fine for big-endian XRGB8888 and ARGB8888, which are
mapped to the existing little-endian BGRX8888 and BGRA8888 formats, it
does not work for big-endian XRGB1555 and RGB565, as the latter are not
listed in the format database.
Fix this by adding the missing formats. Limit this to big-endian
platforms, as there is currently no need to support these formats on
little-endian platforms.

Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,

[ Upstream commit 436864095a95fcc611c20c44a111985fa9848730 ]
Data passed to user-space with a (SOL_UDP, UDP_GRO) cmsg carries an
int (see udp_cmsg_recv), not a u16 value, as strace confirms:
recvmsg(8, {msg_name=...,
msg_iov=[{iov_base="\0\0..."..., iov_len=96000}],
msg_iovlen=1,
msg_control=[{cmsg_len=20, <-- sizeof(cmsghdr) + 4
cmsg_level=SOL_UDP,
cmsg_type=0x68}], <-- UDP_GRO
msg_controllen=24,
msg_flags=0}, 0) = 11200
Interpreting the data as an u16 value won't work on big-endian platforms.
Since it is too late to back out of this API decision [1], fix the test.

Similarly to commit 022eb8ae8b5e ("ARM: 8938/1: kernel: initialize
broadcast hrtimer based clock event device"), RISC-V needs to initiate
hrtimer based broadcast clock event device before C3STOP can be used.
Otherwise, the introduction of C3STOP for the RISC-V arch timer in
commit 232ccac1bd9b ("clocksource/drivers/riscv: Events are stopped
during CPU suspend") leaves us without any broadcast timer registered.
This prevents the kernel from entering oneshot mode, which breaks timer
behaviour, for example clock_nanosleep().

Add sock_init_data_uid() to explicitly initialize the socket uid.
To initialise the socket uid, sock_init_data() assumes a the struct
socket* sock is always embedded in a struct socket_alloc, used to
access the corresponding inode uid. This may not be true.
Examples are sockets created in tun_chr_open() and tap_open().

When encountering a string bigger than the destination buffer (32 bytes),
the string is not properly NUL-terminated, causing buffer overreads later.
This for example happens on the Inspiron 3505, where the battery
model name is larger than 32 bytes, which leads to sysfs showing
the model name together with the serial number string (which is
NUL-terminated and thus prevents worse).
Fix this by using strscpy() which ensures that the result is
always NUL-terminated.

Syzkaller detected a memory leak of skbs in ath9k_hif_usb_rx_stream().
While processing skbs in ath9k_hif_usb_rx_stream(), the already allocated
skbs in skb_pool are not freed if ath9k_hif_usb_rx_stream() fails. If we
have an incorrect pkt_len or pkt_tag, the input skb is considered invalid
and dropped. All the associated packets already in skb_pool should be
dropped and freed. Added a comment describing this issue.
The patch also makes remain_skb NULL after being processed so that it
cannot be referenced after potential free. The initialization of hif_dev
fields which are associated with remain_skb (rx_remain_len,
rx_transfer_len and rx_pad_len) is moved after a new remain_skb is
allocated.

[ Upstream commit e1d9148582ab2c3dada5c5cf8ca7531ca269fee5 ]
Microsoft introduced support in Windows XP for blocking port I/O
to various regions. For Windows compatibility ACPICA has adopted
the same protections and will disallow writes to those
(presumably) the same regions.
On some systems the AML included with the firmware will issue 4 byte
long writes to 0x80. These writes aren't making it over because of this
blockage. The first 4 byte write attempt is rejected, and then
subsequently 1 byte at a time each offset is tried. The first at 0x80
works, but then the next 3 bytes are rejected.
This manifests in bizarre failures for devices that expected the AML to
write all 4 bytes. Trying the same AML on Windows 10 or 11 doesn't hit
this failure and all 4 bytes are written.
Either some of these regions were wrong or some point after Windows XP
some of these regions blocks have been lifted.
In the last 15 years there doesn't seem to be any reports popping up of
this error in the Windows event viewer anymore. There is no documentation
at Microsoft's developer site indicating that Windows ACPI interpreter
blocks these regions. Between the lack of documentation and the fact that
the writes actually do work in Windows 10 and 11, it's quite likely
Windows doesn't actually enforce this anymore.
So to help the issue, only enforce Windows XP specific entries if the
latest _OSI supported is Windows XP. Continue to enforce the
ALWAYS_ILLEGAL entries.
