[PATCH] mei: vsc: Remove unused irq functions

[PATCH] mei: vsc: Remove unused irq functions

[linux]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

vsc_tp_request_irq() and vsc_tp_free_irq() last uses were removed in 2024
by
commit 9b5e045029d8 ("mei: vsc: Don't stop/restart mei device during system
suspend/resume")

Remove them.

Alexander pointed me at this patch because I just posted
almost the same patch:

https://lore.kernel.org/lkml/20250623085052.12347-2-hansg@kernel.org/

Normally I would say lets go with your (David's) version since
you posted your patch first.

But your patch is missing the removal of the function prototypes
from vsc-tp.h, so in this case I think we should go with my version.

Regards,

Hans

Ok, I'll go take your series now, sorry for the delay.
