[PATCH] powerpc: ps3: mark ps3_notification_device static for stack usage

From: Arnd Bergmann
Date: Wed Mar 20 2024 - 14:03:50 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

The device is way too large to be on the stack, causing a warning for
an allmodconfig build with clang:

arch/powerpc/platforms/ps3/device-init.c:771:12: error: stack frame size (2064) exceeds limit (2048) in 'ps3_probe_thread' [-Werror,-Wframe-larger-than]
771 | static int ps3_probe_thread(void *data)

There is only a single thread that ever accesses this, so it's fine to
make it static, which avoids the warning.

Fixes: b4cb2941f855 ("[POWERPC] PS3: Use the HVs storage device notification mechanism properly")
