Subject: [media] Fix cx88 remote control input
From: Lawrence Rust <[email protected]>
commit 2a164d02dd34c6b49a3f0995900e0f8af102b804 upstream.
In the IR interrupt handler of cx88-input.c there's a 32-bit multiply
overflow which causes IR pulse durations to be incorrectly calculated.
This is a regression caused by commit 2997137be8eba.
