So when trying to zeroout or fix the extent length, call ext4_find_extent() to update the path. In addition we use *ppath directly as an ext4_ext_show_leaf() input to avoid possible use-after-free when EXT_DEBUG is defined, and to avoid unnecessary path updates.

[PATCH 5.10] ntfs: do not dereference a null ctx on error

by George Rurikov

From: George Ryurikov <g.ryurikov(a)securitycode.ru> Danila Chernetsov <listdansp(a)mail.ru> commit aa4b92c5234878d55da96d387ea4d3695ca5e4ab upstream. In ntfs_mft_data_extend_allocation_nolock(), if an error condition occurs prior to 'ctx' being set to a non-NULL value, avoid dereferencing the NULL 'ctx' pointer in error handling.

[PATCH] HID: plantronics: Workaround for an unexcepted opposite volume key

by Wade Wang

Some Plantronics headset as the below send an unexcept opposite volume key's HID report for each volume key press after 200ms, like unecepted Volume Up Key following Volume Down key pressed by user. This patch adds a quirk to hid-plantronics for these devices, which will ignore the second unexcepted opposite volume key if it happens within 220ms from the last one that was handled. Plantronics EncorePro 500 Series (047f:431e) Plantronics Blackwire_3325 Series (047f:430c) The patch was tested on the mentioned model, it shouldn't affect other models, however, this quirk might be needed for them too. Auto-repeat (when a key is held pressed) is not affected per test result.

[PATCH] r8169: add tally counter fields added with RTL8125

by Heiner Kallweit

RTL8125 added fields to the tally counter, what may result in the chip dma'ing these new fields to unallocated memory. Therefore make sure that the allocated memory area is big enough to hold all of the tally counter values, even if we use only parts of it.

Regression in 6.11.2

by Mario Limonciello

Hi, commit 872b8f14d772 ("drm/amd/display: Validate backlight caps are sane") was added to stable trees to fix a brightness problem on one laptop on a buggy firmware but with how aggressive it was it caused a problem on another. Fortunately the problem on the other was already fixed in 6.12 though! commit 87d749a6aab7 ("drm/amd/display: Allow backlight to go below `AMDGPU_DM_DEFAULT_MIN_BACKLIGHT`") Can that commit please be brought everywhere that 872b8f14d772 went? Thanks!
