WATCHDOG UAF AND DIVISION-BY-ZERO FIXES LAND IN V7.2-RC5

Linus merged critical watchdog subsystem patches addressing a use-after-free vulnerability and a zero-division crash that could tank embedded systems in production.

The watchdog pull [1] brings four critical fixes: a UAF in the pretimeout governor that could trigger on unregister, a division-by-zero in airoha when clock frequency reads as zero, a NULL pointer dereference in ni903x_wdt, and incorrect flags in s32g_wdt's watchdog_info struct. In parallel, the x86 platform drivers pull [2] reverts an asus-wmi battery charge threshold change that broke userspace tooling, a reminder that sysfs semantics matter more than you think. Liveupdate merged a merge-conflict fix [3] in the GET_NAME ioctl validation, and audio pulled a batch of ALSA core fixes [4] including race conditions and leaks in the timer and sequencer subsystems. Over at Basecamp, omarchy shed technical debt [5] [6] [7] by removing the menu keywords feature and redundant command checks while restoring Plymouth unlock theming [8]. Archinstall fixed translation pipeline breakage [9] [10] where binding descriptions were dropping from base.pot on regeneration, and switched lsblk invocations to use the run command [11] [12].
