[RFC PATCH 0/2] ASoC: atmel: ac97c: Fix IRQ handling sequences

From: Manish Baing

Date: Thu Jun 04 2026 - 16:45:30 EST


This series addresses two hardware initialization and teardown issues in
the atmel_ac97c driver flagged by the Sashiko AI bot.
The original report can be found here:
https://sashiko.dev/#/patchset/20260530052812.115994-1-manishbaing2789@xxxxxxxxx?part=1

- Patch 1 moves request_irq() to the end of probe to prevent a null pointer
dereference if an interrupt fires early.
- Patch 2 reorders the teardown sequence to free the IRQ before disabling
clocks and unmapping memory, preventing a use-after-free.

I am submitting this as an RFC because I do not have the physical hardware
to test these changes, However, my manual analysis indicates these are
valid bugs, and the series compiles cleanly with W=1.
