Linux Kernel Daily: Late-Cycle Stability Fixes for RTC, MTD, and ARC
Three fix merges for real-time clocks, flash storage, and ARC landed for Linux 7.3. The pattern is late-cycle hardening around interrupt setup, hardware capability handling, and small robustness bugs, many flagged by automated review.

Good morning, it's September 30th, 2026, and you're listening to Linux Kernel Daily.
Today's takeaway is late-cycle stability, with three fix merges aimed at preventing regressions in the 7.3 release rather than adding features.
Our first theme is interrupt setup ordering. Both the real-time clock spear driver in commit 551c722 and the Cadence flash controller in commit a243ede fix the same mistake: initializing interrupt state before requesting the interrupt. For developers, that ordering matters because requesting too early can trigger a…
Our second theme is respecting what hardware can actually do. The E F I clock change restores alarm support by probing capabilities at runtime, avoiding a regression on platforms where alarms behave differently. In flash storage, the S-P-I NAND fixes stop updating the Q-E bit on devices that don't have one, while…
Our third theme is automated findings catching classic robustness bugs. Several fixes in these merges are attributed to A-I review and fuzzing, including zeroing a wake alarm structure to prevent an information leak, fixing a use-after-free in the clock provider, a leaked lock in S-P-I NOR, and divide-by-zero and…
