5.15-stable review patch. If anyone has any objections, please let me know.

From: Finn Thain <fthain@xxxxxxxxxxxxxx>
[ Upstream commit d301a71c76ee4c384b4e03cdc320a55f5cf1df05 ]
The via-macii ADB driver calls request_irq() after disabling hard
interrupts. But disabling interrupts isn't necessary here because the
VIA shift register interrupt was masked during VIA1 initialization.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
