regulator: gpio: Add input_supply support in gpio_regulator_config

2025-07-10T13:57:48+00:00

[ Upstream commit adfdfcbdbd32b356323a3db6d3a683270051a7e6 ]

This is simillar as fixed-regulator.
Used to extract regulator parent from the device tree.

Without that property used, the parent regulator can be shut down (if not an always on).
Thus leading to inappropriate behavior:
On am62-SP-SK this fix is required to avoid tps65219 ldo1 (SDMMC rail) to be shut down after boot completion.

usb: typec: altmodes/displayport: do not index invalid pin_assignments

2025-07-10T13:57:43+00:00

commit af4db5a35a4ef7a68046883bfd12468007db38f1 upstream.

A poorly implemented DisplayPort Alt Mode port partner can indicate
that its pin assignment capabilities are greater than the maximum
value, DP_PIN_ASSIGN_F. In this case, calls to pin_assignment_show
will cause a BRK exception due to an out of bounds array access.

Prevent for loop in pin_assignment_show from accessing
invalid values in pin_assignments by adding DP_PIN_ASSIGN_MAX
value in typec_dp.h and using i < DP_PIN_ASSIGN_MAX as a loop
condition.

Revert "ipv6: save dontfrag in cork"

2025-07-10T13:57:42+00:00

This reverts commit 2b572c40981138349c04b3f69220ac878a36c561 which is
commit a18dfa9925b9ef6107ea3aa5814ca3c704d34a8a upstream.

A regression was introduced when backporting this to the stable kernels
without applying previous commits in this series.

When sending IPv6 UDP packets larger than MTU, EMSGSIZE was returned
instead of fragmenting the packets as expected.

As there is no compelling reason for this commit to be present in the
stable kernels it should be reverted.

vsock/uapi: fix linux/vm_sockets.h userspace compilation errors

2025-07-10T13:57:38+00:00

[ Upstream commit 22bbc1dcd0d6785fb390c41f0dd5b5e218d23bdd ]

If a userspace application just include  will fail
to build with the following errors:

    /usr/include/linux/vm_sockets.h:182:39: error: invalid application of ‘sizeof’ to incomplete type ‘struct sockaddr’
      182 |         unsigned char svm_zero[sizeof(struct sockaddr) -

          |

Include  for userspace (guarded by ifndef __KERNEL__)
where `struct sockaddr` and `sa_family_t` are defined.
We already do something similar in  and .

tty: vt: make consw::con_switch() return a bool

2025-07-10T13:57:37+00:00

[ Upstream commit 8d5cc8eed738e3202379722295c626cba0849785 ]

The non-zero (true) return value from consw::con_switch() means a redraw
is needed. So make this return type a bool explicitly instead of int.
The latter might imply that -Eerrors are expected. They are not.

And document the hook.

tty: vt: sanitize arguments of consw::con_clear()

2025-07-10T13:57:37+00:00

[ Upstream commit 559f01a0ee6d924c6fec3eaf6a5b078b15e71070 ]

In consw::con_clear():
* Height is always 1, so drop it.
* Offsets and width are always unsigned values, so re-type them as such.

This needs a new __fbcon_clear() in the fbcon code to still handle
height which might not be 1 when called internally.

Note that tests for negative count/width are left in place -- they are
taken care of in the next patches.

And document the hook.

tty/vt: consolemap: rename and document struct uni_pagedir

[ Upstream commit 4173f018aae16b6496d292c234b858241f85254f ]

struct uni_pagedir contains 32 unicode page directories, so the name of
the structure is a bit misleading. Rename the structure to uni_pagedict,
so it looks like this:
struct uni_pagedict
  -> 32 page dirs
     -> 32 rows
       -> 64 glyphs
